Моделирование тенденций временных рядов со структурными изменениями с помощью многослойных модульных регрессий
Authors: М. П. Базилевский
Published: November 2024

статья посвящена проблеме моделирования технических и социальноэкономических систем, динамика которых трансформируется за счет структурных изменений, что приводит к модификации параметров описывающих эту динамику трендов. Сформулирована трендовая модель многослойной модульной регрессии. Задача ее идентификации с помощью метода наименьших модулей формализована в виде задачи частично-булевого линейного программирования. С помощью предложенных моделей решено 3 задачи моделирования по временным рядам, содержащим тенденцию со структурными изменениями. Первая задача решена по данным о численности населения в Иркутской области, вторая и третья — по данным о грузовых и пассажирских железнодорожных перевозках. Построенные многослойные модульные регрессии, в отличие от линейных трендов, успешно выявили абсолютно все скрытые структурные изменения. Графически проиллюстрировано, как улучшается качество аппроксимации трендовых регрессий с ростом количества их слоев. Наиболее адекватные модели для каждой задачи были представлены в виде кусочно-заданных функций, что позволило дать им содержательную интерпретацию. Достоинство трендовых многослойных модульных регрессий в том, что на этапе оценивания автоматически определяются моменты времени, в которых меняется направление трендов.

this study addresses the challenge of modeling technical and socio-economic systems whose dynamics evolve due to structural changes, resulting in shifts in the parameters of the trends that describe these dynamics. A trend model based on multilayer modular regression is proposed. The identification problem is formalized as a mixed 0-1 integer linear programming problem, solved using the least absolute deviations method. The efficacy of the proposed models is demonstrated through three case studies using time series that exhibit structural changes in their trends. The first case study focuses on population data from the Irkutsk region, while the second and third analyze freight and passenger rail transportation data. Unlike linear trend models, the multilayer modular regressions successfully identified all latent structural changes. Graphical illustrations demonstrate how increasing the number of regression layers enhances the quality of trend approximation. The most appropriate models for each case are presented as piecewise functions, enabling a meaningful interpretation of the results. The primary advantage of multilayer modular trend regressions is their ability to automatically detect time points at which trend directions change during the estimation process.

в своей последней публикации в «Успехах физических наук» по проблеме квантового сознания М. Б. Менский (2007 г.) объединяет все три «великие» проблемы В. Л. Гинзбурга в одну общую проблему. Это проблема необратимости на молекулярном уровне (в термодинамике). Такая необратимость (движения материи) компенсируется некими усредненными (статистически) величинами. Это температура, давление, энтропия. Однако у биосистем уже нет таких констант. Из-за эффекта Еськова–Зинченко статистическая усредненность не может быть применима. Появляется принципиальная неопределенность, и необходимы новые подходы.

in his publication in Uspekhi Fizicheskikh Nauk on quantum consciousness, M.B. Mensky (2007) integrates all three of V.L. Ginzburg’s “great” problems into a unified framework, focusing on the issue of irreversibility at the molecular level within thermodynamics. This irreversibility, representing the motion of matter, is typically compensated for by statistically averaged values such as temperature, pressure, and entropy. However, in biological systems, these constants do not apply. Due to the Eskov–Zinchenko effect, statistical averaging becomes inapplicable, leading to a state of fundamental uncertainty. Consequently, new approaches are required to address these complexities.
Фрактально-голографическая процессуальность в развитии природы сознания
Authors: Б. А. Богатых
Published: November 2024

рассмотрены ключевые вопросы фрактально-голографического конструкта (ФГК) в различных его проявлениях — кластеризации, аттракторно-репеллерной природы — головного мозга, развития природы психического и природы сознания в процессе эмансипации ребенка. Рассмотрен спектр поэтапно и постепенно развивающихся и формирующихся механизмов саморегуляции личности, осуществляющихся при задействовании уже на самых ранних этапах развития ребенка как гомеостатических ФГК-аттракторов, так и фрактально-кластерной архитектуры, а точнее — фрактальноголографической кластеризации. Выдвинуто предположение, что фрактально-голографическая кластеризация используется в обоих направлениях — когда данная точка распадается на ту или иную совокупность точек, т. е. некий кластер, так и при обратном процессе, т. е. при ассиметричном ответе. Данная процессуальность объясняется преимущественно в рамках природы аттрактора Плыкина, способствуя как развитию ребенка, так и формированию его сознания и творческих способностей.

this study explores the key aspects of the fractal-holographic construct (FHC) in its various manifestations, including clustering, the attractor-repeller nature of the brain, and the development of mental processes and consciousness during child emancipation. The gradual emergence and development of personality self-regulation mechanisms are examined, occurring through the use of both homeostatic FHC attractors and a fractal-cluster architecture, particularly through fractal-holographic clustering, even at the earliest stages of a child’s development. It is proposed that fractal-holographic clustering functions bidirectionally – where a single point divides into a set of points, forming a cluster, and through a reverse process, in which a set of points forms an asymmetric response. This dynamic is primarily explained within the framework of the Plykin attractor, which plays a role in both the child’s development and the growth of their consciousness and creative abilities.
Determining the Relationship Between Economic Growth, Carbon Emission and Energy Consumption: Panel Cointegration and Causality Approach in G20 Countries
Authors: Göktolga Ziya Gökalp
Published: November 2024

As it is known, CO2 is a greenhouse gas. Greenhouse gases contained in fossil fuels mix with the atmosphere and cause global warming on earth. Global warming causes many negative situations such as irregular rainfall, drought, difficulties in accessing fresh water, and changes in living biology. Thus, life on earth is becoming increasingly threatened. In this study, the relationship between CO2 emissions and renewable and fossil-based energy use, which are among the factors affecting economic growth, was applied in G-20 countries with panel data analysis. The data of the study were collected from the World Bank. A total of 589 data were studied in 19 countries and 31 time dimensions. AMG method was used for long-term estimation of the data by performing cross-section dependence, unit root tests and homogeneity tests. Granger causality test was performed between the variables. A positive relationship was found between GDP growth and CO2, and it was found that a one-unit increase in CO2 use would cause a 0.88-unit increase in GDP growth. Additionally, the study found that there is a unidirectional causality from renewable energy, fossil energy consumption and CO2 usage to GDP growth.

Published: November 2024

Abstract. Coastal zones are increasingly acknowledged as dynamic yet fragile components of global ecosystems amidst escalating anthropogenic activities and complex land-ocean interactions. Understanding the interactions between groundwater and the ocean is crucial for managing submarine groundwater discharge (SGD) and seawater intrusion (SWI), vital for coastal ecosystem preservation and water resource management. This research proposes an integrated modeling approach that couple groundwater flow and physical oceanographic models to accurately simulate coastal-ocean groundwater interactions. In this work, a TELEMAC-3D based three-dimensional hydrodynamic model was initially developed to capture marine conditions with variable salinity and temperature. A MODFLOW6 groundwater model was subsequently constructed. The models were efficiently coupled using Flopy and Telapy, enabling precise co-simulation of hydrodynamic and groundwater systems. Validation of the coupled model against empirical data confirmed its high fidelity, with errors within acceptable ranges. This coupled model employs dynamic boundary conditions, overcoming the limitations of traditional coastal groundwater models that assume constant salinity. This enhancement significantly improves the accuracy and practicality of simulating SGD processes in the coastal ocean. The bidirectional feedback mechanism within the coupled model strengthens the analysis of interactions between the ocean and groundwater systems. It accounts for variations in the seawater boundary under tidal influence and the reciprocal impact of groundwater dynamics on the hydrodynamic conditions of nearshore waters. This holistic enhancement bolsters the model's hydrological simulation capabilities, providing a more comprehensive depiction of the intricate water-salt exchange mechanisms in coastal systems.
Do data-driven models beat numerical models in forecasting weather extremes? A comparison of IFS HRES, Pangu-Weather, and GraphCast
Authors: Olivetti Leonardo , Messori Gabriele
Published: November 2024

Abstract. The last few years have witnessed the emergence of data-driven weather forecast models capable of competing with – and, in some respects, outperforming – physics-based numerical models. However, recent studies have questioned the capability of data-driven models to provide reliable forecasts of extreme events. Here, we aim to evaluate this claim by comparing the performance of leading data-driven models in a semi-operational setting, focusing on the prediction of near-surface temperature and wind speed extremes globally. We find that data-driven models mostly outperform ECMWF’s physics-based deterministic model in terms of global RMSE for forecasts made 1–10 d ahead and that they can also compete in terms of extreme weather predictions in most regions. However, the performance of data-driven models varies by region, type of extreme event, and forecast lead time. Notably, data-driven models appear to perform best for temperature extremes in regions closer to the tropics and at shorter lead times. We conclude that data-driven models may already be a useful complement to physics-based forecasts in regions where they display superior tail performance but note that some challenges still need to be overcome prior to operational implementation.
Global and local endmembers spectral patterns to estimate the urban structure in Porto Alegre (Brazil) in Landsat images using the Linear Spectral Mixture Model procedure
Authors: Hirye Mayumi Cursino de Moura , da Fonseca Eliana Lima
Published: November 2024

Abstract. This study investigates the spectral patterns of global and local endmembers to assess urban structure estimation within Porto Alegre city, Brazil. Two distinct sets of endmembers were examined: one derived from global patterns acquired from 100 Landsat image subsets and the other from local patterns gathered across 27 analyzed images. Results reveal that the utilization of global endmember patterns tends to overestimate the presence of urban shadow in all analyzed images compared to estimates derived from local patterns. Consequently, this overestimation impacts the relative proportions of other endmembers. Despite the disparities in magnitude between fractions estimated with each set of endmembers, temporal variations exhibit similar interannual trends. The findings of this study suggest that, beyond the choice between standardized or localized models, the features that must be represented in the resulting maps should also be considered in the selection between global and local endmembers.
Multiseasonal analysis of rice crop yield prediction with Sentinel-2 time series and UAV imagery in Lambayeque (Peru)
Authors: Quille-Mamani Javier A. , Ruiz Luis A. , Ramos-Fernández Lía
Published: November 2024

Abstract. Accurate crop yield prediction is crucial for efficient agricultural and socio-economic management. Remote sensing, using satellite imagery and unmanned aerial vehicles (UAVs), provides an effective approach for yield prediction and crop monitoring, allowing time series of vegetation indices such as NDVI to be obtained and facilitating detailed analysis of crop phenology. In this study, multi-seasonality in rice yield prediction is analysed using NDVI time series obtained from Sentinel-2 (S2) and UAVs in the Lambayeque region, Peru. NDVI from S2 was extracted by applying scene classification map (SCM) masks to remove clouds and shadows. A total of 7 and 11 UAV flights were conducted during the growing season for 2022 and 2023, and yield was collected mechanically in 35 rice-producing plots. The results showed an overestimation of NDVI values obtained by UAV compared to Sentinel-2 values, as well as a significant difference in yield prediction between 2022 and 2023. In 2022, by integrating S2 and UAV NDVI series, a coefficient of determination (R2) of 0.66 was obtained for the combination of UAV and S2, higher value than those obtained with UAV or S2 independently, with a root mean square error (RMSE) of 1.096 t/ha and a %RMSE of 10.36. In 2023, a R2 of 0.32, a RMSE of 0.85 and a %RMSE of 9.21 were achieved. This difference is interpreted as a consequence of the cyclone Yaku, which caused rainfall and damage to the irrigation infrastructure, and fungi disease, leading to water stress and a decrease in yield, highlighting the importance of considering the meteorological conditions in the development of yield predictions based on NDVI series metrics obtained along the campaign.

Published: November 2024

Abstract. The volcanic island of Stromboli (southern Tyrrhenian Sea, Italy) is renowned for its persistent, periodic, low-intensity explosive activity, whose spectacular manifestations attract tens of thousands of tourists every year. However, sporadic more intense major explosive and effusive eruptions and paroxysms pose serious threats to the island. In addition to direct hazards, granular slides of volcanic debris and pyroclastic avalanches, which can rapidly reach the sea and potentially generate tsunamis, are often associated with such unpredictable eruptive activity. Due to the very fast propagation of the tsunami around the island and the consequent short tsunami warning time (ranging from less than a minute to only a few minutes), mitigation efforts and evacuation from the Strombolian coast must be carefully planned. In this paper, we describe a new GIS-assisted procedure that allows us to combine the outputs of an ensemble of 156 pre-computed landslide-generated tsunami hazard scenarios (with variable landslide volume, position, and density), statistical exposure data (i.e. the number of inhabitants and tourists), and digital geographic information to obtain a quantitative (scenario-based) risk analysis. By means of the analysis of the road network and coastal morphology, we develop a model with routes and times to reach a safe area from every pixel in the inundated area and an appraisal of the time needed to escape versus the wave arrival time. This allows us to evaluate and quantify the effectiveness of potential risk mitigation by means of evacuation. The creation of an impact score linking the predicted inundation extent and the tsunami warning signals is intended, in the long term, to be used to predict the intensity of future tsunamis and to adapt evacuation plans accordingly. The model, here applied to Stromboli, is general and can be applied to other volcanic islands. Evacuating an island hosting several thousand tourists every summer with very little warning time underlines the absolute necessity for such mitigation efforts, aimed at informing hazard planners and managers and all other stakeholders.
Evaluating the potential of a wake steering co-design for wind farm layout optimization through a tailored genetic algorithm
Authors: Baricchio Matteo , Gebraad Pieter M. O. , van Wingerden Jan-Willem
Published: November 2024

Abstract. Wake steering represents a viable solution to mitigate the wake effect within a wind farm. New research that considers the effect of the control strategy within the layout optimization is emerging, adopting a co-design approach. This study estimates the potential of this technique within the layout optimization for a wide range of realistic conditions. To capture the benefits of such methods, a genetic algorithm tailored to the layout optimization problem has been developed in this work; hence this is referred to as a layout optimization genetic algorithm (LO-GA). The crossover phase is designed to recognize and exploit the differences and the similarities between parent layouts, whereas the randomness of the mutation is limited to improve the exploration of the design space. New relations have been introduced to calculate the geometric yaw angles based on the reciprocal positions between the turbines. For a base case of 16 turbines located at the Hollandse Kust Noord site, a gain in the annual energy production (AEP) between 0.3 % and 0.4 % is obtained when the co-design approach is adopted. This increases up to 0.6 % for larger farms, saturating after 25 turbines. However, the benefit of the co-design decreases in the case of low power densities or if the wind resource is highly unidirectional. On the other hand, in the case that wake steering is not applied during the operation of the farm, a decrease in the AEP up to 0.6 % is registered for a layout optimized with the co-design method. To prevent the risk related to future decisions on the control strategy, a multi-objective co-design approach is proposed. This is based on the simultaneous optimization of the layout for a scenario in which wake steering is applied versus a case where wake steering is not adopted during the operation of the farm. We have concluded that the solutions obtained with this method ensure an AEP gain higher than 0.3 % for a 16-turbine farm while limiting the loss to below 0.1 % in the case that wake steering is not applied. However, these AEP gains are affected by the size of the wind direction bins adopted in the simulations, enhancing the necessity of taking into account the wind direction errors and the yaw actuation constraints for a realistic evaluation of the co-design approach.

Published: November 2024

The study aimed to assess the immediate effects of re-warm-up strategies using half-squats with elastic looped bands on the performance of youth soccer players. A cross-over study design with repeated measures was implemented in field youth male soccer players (n = 20, age 15.7 ± 0.8 years). Following the first 45-min of match play, players were subjected to one of four re-warm-up (Re-w) interventions of equal duration: no Re-w (PAS), half-squat without elastic looped bands (SQ), half-squat with bands placed on the thighs (SQT), and half-squat with bands placed on the lower legs (SQL). These interventions were compared against a control condition (CON). The Re-w protocols were initiated 10-min after half-time, and players' performance was evaluated through vertical and horizontal jump tests, 20-m linear sprint, and T-agility test. Statistical analysis using ANOVA revealed that the SQT and SQL interventions significantly improved (p < 0.001) several performance metrics compared to the PAS and SQ conditions. These improvements were observed in squat jumps, unilateral squat jumps (both dominant and non-dominant legs), countermovement jumps, horizontal jumps, triple horizontal jumps, the 20-m linear sprint, and T-agility performance. In conclusion, SQT and SQL are equally effective to enhance performance as Re-w strategies after the 1st-half of a soccer match. However, the lack of physiological data and 2nd-half assessments suggests the need for further research to confirm the persistence of these effects.

This study aims to explore the implementation of character education in building noble morals among Grade VIII students at MTs Darul Hadist Hutabaringin in Mandailing Natal Regency. The research adopts a qualitative approach using a case study method, where data is collected through observation, in-depth interviews, and documentation. The research subjects include students, teachers, the head of the madrasah, and parents. The findings reveal that character education at MTs Darul Hadist Hutabaringin is integrated into daily learning through teacher role models, extracurricular activities such as scouting and spiritual studies, and parental involvement in supporting school programs. Teachers play a significant role in instilling moral values, while extracurricular activities provide a space for students to practice these values outside the classroom. The study also identifies challenges, such as external environmental influences, particularly social media, which may hinder students’ internalization of character values. Additionally, limitations in time and resources pose obstacles to the optimal implementation of character education. The study concludes by emphasizing the importance of stronger collaboration between schools, parents, and the community to reinforce character education. Continuous evaluation and innovation are also necessary to address technological challenges, ensuring character education remains relevant and effective in shaping a morally upright generation.
From Belief to Practice: Understanding Response to Intervention (RTI) or Multi-Tiered System of Supports (MTSS), Implementation among Primary School Teachers
Authors: Nasim Farhat , Khan Erum Aslam , Hussain Sarfraz , Shoqat Inza
Published: November 2024

The Multi-Tiered System of Supports (MTSS), also known as Response to Intervention (RTI), is an educational reform initiative aimed at providing quality education and evidence-based treatments for all students. The main objective of the study was to investigate how teachers perceive the beliefs and practices regarding the RTI/MTSS process. The quantitative survey design was used to achieve the main goal for this study. Primary school teachers of these two districts (Multan and Jehlum) were considered a population regardless of their gender. 700 teachers were selected using a stratified random sampling method. A 34-item self-developed questionnaire was used to collect data. Inferential data analysis was used to compare the teachers' beliefs and practices about the RTI/MTSS process with demographic characteristics like location, gender, district, and teaching experiences. The study's results show that teachers had stable and clear ideas about the RTI/MTSS process. Although the teachers saw a moderate and small improvement in their practices, this suggests that their beliefs and actions did not match. The study also established that there were statistical differences in perceived norms between the male and female teachers, the teachers from the different districts, and the teachers with different experience in teaching, but no difference in vignette practices. Further research may attempt to investigate the commonality of the intervention process that has been effective at increasing rates and establish potentially teachable strategies in independent practice.

Published: November 2024

The aim of this research is to explore the lived experiences of families providing care at home for medical technology dependent children focusing on its emotional, social and psychological impact along with highlighting how the family members cope with their daily challenges and the strategies they employ to maintain family wellbeing. Medical technology dependent children are those who require special health needs in terms of an external equipment to substitute for the loss of an essential bodily function or to ensure their survival. As an example, they need a complex treatment regimen using devise like mechanical ventilation or tracheotomy (Okido, Zago, & Lima, 2015). This research contributes to the existing literature by deepening the understanding of the caregivers’ challenges on looking after such children from a multifaceted perspective within the context of Pakistan. A phenomenological qualitative research design was used (Ho & Limpaecher, 2022). In-depth interviews were conducted from six families having a medical technology dependent child. The data was analyzed using an interpretative phenomenological analysis in a series of steps (Creswell & Poth, 2016). The analysis of the data yielded an overarching theme, major living challenges having the subthemes; psychological factors, social issues, and financial constraints.

As part of a pedagogical experiment conducted at the Technical University of Moldova (TUM), 259 students were evaluated post-experimentally to analyze the effectiveness and long-term impact of these strategies on academic performance and the development of professional skills. The results demonstrated that the implementation of the e-learning-centered pedagogical model led to significant improvements in students' cognitive, emotional, and behavioral engagement, thus confirming the sustainability and relevance of these instructional methods. The contribution of this study lies in highlighting the academic and scientific value of effectively integrating e-learning strategies into the university educational process, as well as in formulating well-founded recommendations for optimizing e-learning strategies to meet the current demands of higher education.
AFROCENTRIC PEDAGOGY APPROACH IN THE CURRICULUM OF EDUCATIONAL SYSTEM RENEWAL IN AFRICA: A CASE OF SOUTH AFRICA
Authors: Selelo Mohale Ernest , Manamela Madumetsa Godfrey
Published: November 2024

The purpose of this paper is to conceptualize in greater detail the educational system approach that is being imposed into African countries, South Africa as a case in point. Over the past years, Sub-Saharan countries have and still experience indoctrinated educational system in which the content is mimicked from purported hegemonic states such UK, USA and other western counties inter alia. The problem of education retrogrades from the prior independence of African countries in the early 1960s wherein, the colonial masters organized and silently played a crucial role in shaping the formation of education in Africa; and not much has changed in terms of education since then. A particular concern is that the system of education might have designed to impoverish African people and perpetuate dependency to the western nations. Hence, at the core center of the educational system is the curriculum which seem to be inevitable and requires an alteration, particularly in South Africa. Therefore, the outlook of this paper is to critique and interrogate the system of education in South Africa looking at the socio-economic development and a continuous alteration in respect of the curriculum. The paper shows that for the realization of African renaissance, ideals of Africa Agenda 2063 and accelerated development, the system of education must be transformed and be Africanized to benefit the people of Africa. The paper uses literature-based approach as a methodological framework in order to analyze the status quo of education in South Africa. The paper concludes and recommends that the transformation of current educational system requires an alteration to the inclusive of indigenous knowledge to vigorously respond to socio-economic woes in Africa. Furthermore, the paper advocates for indigenous knowledge consideration in the incessant curriculum renewal.
PERSPECTIVES FOR THE DEVELOPMENT OF SCIENCE IN THE SOCIETY

The world has never been so open to scientific research and technological development as it is today, nor has human competence evolved so rapidly in directions not previously appreciated. The pace of discoveries is faster, although there are scientific fields in which goals are achieved more slowly and with considerable collective effort. However, we find that the successes achieved in the field of science have had an enormous impact on people's mentality and as a consequence have formed the belief that reflects science as a dominant factor in contemporary society. A philosophical reflection on the process of scientific development reveals that for a long time, the physical sciences have been dominant, and in recent years we are witnessing a fulminating development of biology (genetics), which has not only economic implications but also the ethical implications of a major importance. At the same time, the contemporary society of information and knowledge attests to obvious factors of a unique phenomenon called integrative science. It is projected at the integrative frontier of the astrophysics field that combines the processes of the universe constitution as a quantum system (processes that go beyond the theory of quantum mechanics, but also the theory of super lathes) and the processes of life, mind and consciousness. Integrative science proposes a new understanding of reality, even the one considered today purely structural. We hope that integrative science theories will reflect the reality that includes Consciousness as a fundamental factor of Existence.
UNPACKING THE PLACE OF ARCHAEOLOGY AND HERITAGE IN PANDEMIC STUDIES
Authors: Nomishan Terngu Sylvanus
Published: November 2024

Archaeology offers a 3.5 million-year-long scientific record of human and earlier hominine problem-solving and thus has the potential to research very deep into the past human solutions to pandemics and epidemics. Heritage on the other hand acts as a positive enabler for the complex, multi-vector challenges of today’s world, such as cultural and environmental sustainability, economic inequalities, conflict resolution, social cohesion and the future of cities among others. In this way, the remote past has the capacity to educate the present world on how to cope with pandemic diseases and similar challenges in the contemporary era. Therefore, this essay seeks to open a discourse on the ways in which archaeology and heritage can contribute to the prevention and control of the present COVID-19 pandemic and similar others in the present and future. Therefore, the government and other agencies funding research pertaining to the discovery of the ways through which pandemics can be treated, controlled and prevented, need also to explore the option of archaeology and heritage studies, so as to trace the root causes of pandemic diseases. This will lead to the discovery of traditional means of treating, controlling and preventing pandemic outbreaks. This underscores the argument that almost everything that exists in the present day has some historical antecedence.

Credit risk affects the work and reputation of banks. Islamic banks' heavy reliance on debt financing has led to increased interest in credit risk and its management. This paper aimed to identify the bank-specific factors affecting credit risk in Islamic banks, expressed as Non-Performing Finance NPF in the Middle East for the period 2011-2022. The study was based on a panel data analysis of 30 Islamic banks. The findings of study show a significant negative impact of Return On Assets ROA, Capital Adequacy Ratio CAR and size Z on the credit risk. The findings show a significant positive impact of Finance Loss Provision FLP on the credit risk. The findings also show no impact of Finance Expansion FEX, Finance to Deposit Ratio FDR and Capital Ratio CPR on the credit risk. The study showed that increasing the provision for financing losses and capital adequacy helps banks to reduce the impact of credit risks. The study recommends applying cautious lending policies and carefully selecting clients.
A Dynamic Supply Modulator in 18 nm FinFET Node Using Comparator Approach

Published: November 2024

To keep up with the rapid development and to increase spectral efficiency, emerging communication systems like 5G will need to transfer data at speeds significantly faster than those of current systems. The subject of this study is radio frequency (RF) circuit systems, with an emphasis on efficiency enhancement for RF power amplifiers (PA). To cut costs and size, the majority of a smartphone's components are now integrated into a single chip. Regardless of the input signal's magnitude, the fundamental idea behind the envelope tracking (ET) approach is to operate the linear PA in its high-efficiency area. This is achieved by modulating the linear PA's supply voltage, which is as low as 1V, after determining the input signal's magnitude. In view of reducing the chip area and enhancing the efficiency of the PA, an 18nm FinFET node has been used and a comparator-based approach is demonstrated. Keeping the parameters of the 5G specifications in mind, a single-bit comparator is designed to operate at the Sub-6 GHz frequency band with a centre frequency of 3.5 GHz. The propagation delay of the comparator is as low as 67.18ps, and the 8-bit comparator, designed by cascading single-bit comparators, serves as the dynamic power source for the supply modulator. This study provides scope for further development in integrating the comparator with an RF PA for efficiency enhancement. The digital approach of using a comparator instead of bulky circuits provides an upper edge in terms of power consumption and reduction in chip area.  The power consumption of the entire efficiency-enhanced PA in an 18nm FinFET technology is expected to reduce considerably in comparison with the CMOS technology.
