2021 ISSCC Tutorials
Abstract: Fully integrated voltage regulators (FIVRs) enable fast dynamic voltage and frequency scaling for energy-efficient high-performance digital systems. This tutorial will cover the fundamentals of low-dropout regulators (LDOs), as well as switched-capacitor (SC) and inductor-based DC-DC converters. Emphasis will be put on design considerations of analog/digital/mixed control, PID control for FIVR, resonant SC, and hybrid DC-DC converters. Last but not least, we will have a brief review of distributed FIVR designs.
Study of Damage Propagation at the Interface Localization-Delocalization Transition of the Confined Ising Model

description: The propagation of damage in a confined magnetic Ising film, with short range competing magnetic fields ($h$) acting at opposite walls, is studied by means of Monte Carlo simulations. Due to the presence of the fields, the film undergoes a wetting transition at a well defined critical temperature $T_w(h)$. In fact, the competing fields causes the occurrence of an interface between magnetic domains of different orientation. For $T < T_w(h)$ ($T > T_w(h)$) such interface is bounded (unbounded) to the walls, while right at $T_w(h)$ the interface is essentially located at the center of the film. It is found that the spatio-temporal spreading of the damage becomes considerably enhanced by the presence of the interface, which act as a ''catalyst'' of the damage causing an enhancement of the total damaged area. The critical points for damage spreading are evaluated by extrapolation to the thermodynamic limit using a finite-size scaling approach. Furthermore, the wetting transition effectively shifts the location of the damage spreading critical points, as compared with the well known critical temperature of the order-disorder transition characteristic of the Ising model. Such a critical points are found to be placed within the non-wet phase.

description: We report an on-chip single mode microlaser with low-threshold fabricated on Erbium doped lithium niobate on insulator (LNOI). The single mode laser emission at 1550.5 nm wavelength is generated in a coupled photonic molecule, which is facilitated by Vernier effect when pumping the photonic molecule at 970 nm. A threshold pump power as low as 200 uW is demonstrated thanks to the high quality factor above 10^6. Moreover, the linewidth of the microlaser reaches 4 kHz, which is the best result in LNOI microlasers. Such single mode micro-laser lithographically fabricated on chip is highly in demand by photonic community.

2021 ISSCC Tutorials
Abstract: This tutorial presents a practical overview of current-mode and voltage-mode DAC drivers, focusing on the fundamentals, accuracy challenges and design solutions. First, the tutorial explains transmitter specifications for swing, jitter, equalization and linearity, while also introducing DAC performance metrics and discussing their overall impact on wireline systems. Next, the current-mode and voltage-mode DAC architectures are introduced while highlighting the pros and cons of each. High-speed design challenges, bandwidth and non-linearity trade-offs are reviewed. PVT and mismatch effects, swing enhancements and calibration techniques are introduced. The tutorial concludes with several DAC design examples utilizing deep submicron CMOS technologies reaching up to 56Gbaud/s.

description: In order to contribute to the general effort aiming at the improvement of our knowledge about the physical conditions within the Broad Line Region (BLR) of Active Galactic Nuclei (AGN), here we present the results achieved by our analysis of the spectral properties of a sample of 90 broad line emitting sources, collected at the Sloan Digital Sky Survey (SDSS) database. By focusing our attention mainly onto the Balmer series of hydrogen emission lines, which is the dominant feature in the optical wavelength range of many BLR spectra, we extracted several flux and profile measurements, which we related to other source properties, such as optical continuum luminosities, inferred black hole masses, and accretion rates. Using the Boltzmann Plot method to investigate the Balmer line flux ratios as a function of the line profiles, we found that broader line emitting AGN typically have larger H_alpha / H_beta and smaller H_gamma / H_beta and H_delta / H_beta line ratios. With the help of some recent investigations, we model the structure of the BLR and we study the influence of the accretion process on the properties of the BLR plasma.

description: We present a radio morphological study and spectral analysis for a sample of 13 cD galaxies in rich and poor clusters of galaxies.} Our study is based on new high sensitivity Giant Metrewave Radio Telescope (GMRT) observations at 1.28 GHz, 610 MHz and 235 MHz, and on archival data. From a statistical sample of cluster cD galaxies we selected those sources with little information available in the literature and promising for the detection of aged radio emission. Beyond the high sensitivity images for all 13 radio galaxies, we present also a detailed spectral analysis for 7 of them. We found a variety of morphologies and linear sizes, as typical for radio galaxies in the radio power range sampled here (low to intermediate power radio galaxies). The spectral analysis shows that 10/13 radio galaxies have steep radio spectrum, with spectral index $α\ge 1$. In general, the radiative ages and growth velocities are consistent with previous findings that the evolution of radio galaxies at the cluster centres is affected by the dense external medium (i.e. low growth velocities and old ages. We suggest that the dominant galaxies in A 2622 and MKW 03s are dying radio sources, which at present are not fed by nuclear activity. On the other hand, the spectacular source at the centre of A 2372 might be a very interesting example of restarted radio galaxy. For this source we estimated a life cycle of the order of 10$^6$ yr.

description: We propose an extrinsic, continuous-Galerkin (CG), extended finite element method (XFEM) that generalizes the work of Hansbo and Hansbo to allow multiple Heaviside enrichments within a single element in a hierarchical manner. This approach enables complex, evolving XFEM surfaces in 3D that cannot be captured using existing CG-XFEM approaches. We describe an implementation of the method for 3D static elasticity with linearized strain for modeling open cracks as a salient step towards modeling progressive fracture. The implementation includes a description of the finite element model, hybrid implicit/explicit representation of enrichments, numerical integration method, and novel degree-of-freedom (DoF) enumeration algorithm. This algorithm supports an arbitrary number of enrichments within an element, while simultaneously maintaining a CG solution across elements. Additionally, our approach easily allows an implementation suitable for distributed computing systems. Enabled by the DoF enumeration algorithm, the proposed method lays the groundwork for a computational tool that efficiently models progressive fracture. To facilitate a discussion of the complex enrichment hierarchies, we develop enrichment diagrams to succinctly describe and visualize the relationships between the enrichments (and the fields they create) within an element. This also provides a unified language for discussing extrinsic XFEM methods in the literature. We compare several methods, relying on the enrichment diagrams to highlight their nuanced differences.

A Loser: Octave Mirbeau’s Evolution from Populist Right to Libertarian Left
Creators: name: Gemie, Sharif
Publisher: name: Moving the Social
Year: 2015

description: This paper is centred on the political turning-point in the life of Octave Mirbeau, best known as an anarchist journalist, novelist and playwright. Mirbeau’s first political affiliation was to Bonapartism (in the 1870s). In the early 1880s he appeared to be growing closer to some of the ideas of the New Right, and in particular wrote some anti-Semitic material. However, in the period 1883–87 he moved to a clear commitment to anarchism. This paper analyses the multidimensional nature of this turning point, at once cultural, aesthetic, personal and political, and considers the nature of Mirbeau’s anarchism. The most important aspect seems to have been anarchism’s openness to the themes of aesthetic freedom and experimentation.

description: Network tomography has been regarded as one of the most promising methodologies for performance evaluation and diagnosis of the massive and decentralized Internet. This paper proposes a new estimation approach for solving a class of inverse problems in network tomography, based on marginal distributions of a sequence of one-dimensional linear projections of the observed data. We give a general identifiability result for the proposed method and study the design issue of these one dimensional projections in terms of statistical efficiency. We show that for a simple Gaussian tomography model, there is an optimal set of one-dimensional projections such that the estimator obtained from these projections is asymptotically as efficient as the maximum likelihood estimator based on the joint distribution of the observed data. For practical applications, we carry out simulation studies of the proposed method for two instances of network tomography. The first is for traffic demand tomography using a Gaussian Origin-Destination traffic model with a power relation between its mean and variance, and the second is for network delay tomography where the link delays are to be estimated from the end-to-end path delays. We compare estimators obtained from our method and that obtained from using the joint distribution and other lower dimensional projections, and show that in both cases, the proposed method yields satisfactory results.

description: We investigate the structure of subdirect products of groups, particularly their finiteness properties. We pay special attention to the subdirect products of free groups, surface groups and HNN extensions. We prove that a finitely presented subdirect product of free and surface groups virtually contains a term of the lower central series of the direct product or else fails to intersect one of the direct summands. This leads to a characterization of the finitely presented subgroups of the direct product of 3 free or surface groups, and to a solution to the conjugacy problem for arbitrary finitely presented subgroups of direct products of surface groups. We obtain a formula for the first homology of a subdirect product of two free groups and use it to show there is no algorithm to determine the first homology of a finitely generated subgroup.

description: We study the distinct effects of Dark Matter and Dark Energy on the future evolution of nearby large scale structures using constrained N-body simulations. We contrast a model of Cold Dark Matter and a Cosmological Constant (LCDM) with an Open CDM (OCDM) model with the same matter density Omega_m =0.3 and the same Hubble constant h=0.7. Already by the time the scale factor increased by a factor of 6 (29 Gyr from now in LCDM; 78 Gyr from now in OCDM) the comoving position of the Local Group is frozen. Well before that epoch the two most massive members of the Local Group, the Milky Way and Andromeda, will merge. However, as the expansion rates of the scale factor in the two models are different, the Local Group will be receding in physical coordinates from Virgo exponentially in a LCDM model and at a roughly constant velocity in an OCDM model. More generally, in comoving coordinates the future large scale structure will look like a sharpened image of the present structure: the skeleton of the cosmic web will remain the same, but clusters will be more `isolated' and the filaments will become thinner. This implies that the long-term fate of large scale structure as seen in comoving coordinates is determined primarily by the matter density. We conclude that although the LCDM model is accelerating at present due to its Dark Energy component while the OCDM model is non accelerating, their large scale structure in the future will look very similar in comoving coordinates.

2021 ISSCC Tutorials
Abstract: Digitally assisted ADCs have become mainstream. Fine geometry processes and the insatiable need for higher resolution ADCs at higher sample rates have made sophisticated digital assistance a necessity. In this tutorial, we cover some of the advanced calibration techniques for high-speed and high-resolution ADCs. These include techniques to correct for inter-stage gain and settling errors, amplifier non-linearity, memory, DAC and reference errors. The tutorial will discuss the advantages and limitations of the different approaches, some of the practical considerations, and some state-of-the-art examples.

description: In most Yang-Mills models the vacuum where magnetic monopoles condense coincides with that where center vortices percolate, thus it is not clear which of these two properties is most directly involved in producing confinement. It is pointed out that there is a class of 3D gauge models, which can be though of as duals of Q-state Potts models with Q < 1, where the magnetic monopole condensation is a necessary but not sufficient condition for percolation of center vortices. A set of numerical tests at Q=1/10 shows that there is a vacuum in which the magnetic monopole condensate does not yield confinement, in the sense that large Wilson loops obey a perimeter law. In such a vacuum the center vortices form a dilute gas of loops. At stronger coupling there is also a truly confining vacuum where both confining mechanisms are present.

description: Previously, we proved an identity for theta functions of degree eight, and several applications of it were also discussed. This identity is a natural extension of the addition formula for the Weierstrass sigma-function. In this paper we will use this identity to reexamine our work in theta function identities in the past two decades. Hundreds of results about elliptic modular functions, both classical and new, are derived from this identity with ease. Essentially, this general theta function identity is a theta identities generating machine. Our investigation shows that many well-known results about elliptic modular functions with different appearances due to Jacobi, Kiepert, Ramanujan and Weierstrass among others, actually share a common source. This paper can also be seen as a summary of my past work on theta function identities. A conjecture is also proposed.

Radical Carnivalisation of Religion in Erasmus’s The Praise Of Folly
Creators: name: Chaudhury, Sarbani
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2014

description:

This article delineates the conceptual, thematic and structural links of Erasmus’s The Praise of Folly to popular culture and the dynamics of this incorporation that subsumes moral righteousness in riotous wonder (Gordon 121) and lends an anarchic quality to the text despite authorial attempts to inscribe it within the framework of orthodox Christian scepticism. The inability of the ‘professed’ programme to contain and channel the means adopted for its propagation generates a hectic spill-over and highlights the possibility of unearthing repressed implications gravitating towards an acknowledgement of conflict and social dissonance. It also forwards a general critique of social, moral and intellectual hierarchy and privilege through the use of parodic travesty in the first two sections of the book. More significant is the paradoxical insistence on material life divested from the ideological referentials stipulated by established religion in the first part and the climactic evocation of a popular festive non-hierarchical Christian existence as the ultimate manifestation of collective desire. Taken together, Folly’s triptych – celebration, castigation, and renunciation – exemplify a deliberate foregrounding of the faultlines of the accepted schema and of proposing a positive, plebeian antidote.  The complex use of laughter, in both its conciliatory and destructive role, as the principal mode of expression (and response) further problematises the issue. Contrary to the common assumption of an irreducible dichotomy between laughter and philosophy, «laughter is recuperated as philosophy» in The Praise of Folly and constitutes «a way of knowing the truth about the world that is accessible neither to solemn academic discourse nor to the reduced genres of personal satire» (Michael D. Bristol). The article illustrates how the evocation of grotesque, popular, festive laughter by Folly’s ‘learned’ ignorance and her self-referential self-ridicule is, in effect, a ‘carnivalisation’ of religion that seems to be the only mode of attaining truth.

Publisher: name: IEEE

ISSCC Short Course Slides
The performance of high-speed wireline and wireless subsystems highly depends on their clock quality. As data rates continue to scale aggressively, practical understanding of clocking design tradeoffs to optimize system power and area while achieving target bandwidth is crucial. In this short course, different aspects of clocking from circuit implementation to system architecture are discussed to provide insight into challenges and design choices for an optimum clocking solution. Clock generation techniques such as phase-locked loops (PLLs), delay-locked loops (DLLs) and injection-locked oscillators (ILOs) are also discussed. The design tradeoffs among various clock distribution techniques are presented. Clock recovery architectures and their impact on overall system performance are explained. To mitigate process variation, variation-tolerant circuits and clock calibration techniques are required. Energy-efficient clocking solutions can be achieved by active power minimization, amortization and aggressive power management methods. Examples of state-of-the-art clocking circuit and architecture solutions are presented.

description: A very particular connection between the commutation relations of the elements of the generalized Pauli group of a $d$-dimensional qudit, $d$ being a product of distinct primes, and the structure of the projective line over the (modular) ring $\bZ_{d}$ is established, where the integer exponents of the generating shift ($X$) and clock ($Z$) operators are associated with submodules of $\bZ^{2}_{d}$. Under this correspondence, the set of operators commuting with a given one -- a perp-set -- represents a $\bZ_{d}$-submodule of $\bZ^{2}_{d}$. A crucial novel feature here is that the operators are also represented by {\it non}-admissible pairs of $\bZ^{2}_{d}$. This additional degree of freedom makes it possible to view any perp-set as a {\it set-theoretic} union of the corresponding points of the associated projective line.

description: Nonequilibrium steady-state currents, unlike their equilibrium counterparts, continuously dissipate energy into their physical surroundings leading to entropy production and time-reversal symmetry breaking. This letter discusses these issues in the context of quantum impurity models driven out of equilibrium by attaching the impurity to leads at different chemical potentials and temperatures. We start by pointing out that entropy production is often hidden in traditional treatments of quantum-impurity models. We then use simple thermodynamic arguments to define the rate of entropy production. Using the scattering framework recently developed by the authors we show that the rate of entropy production has a simple information theoretic interpretation in terms of the Shannon entropy and Kullback-Leibler divergence of nonequilibrium distribution function. This allows us to show that the entropy production is strictly positive for any nonequilibrium steady-state. We conclude by applying these ideas to the Resonance Level Model and the Kondo model.

description: Recently it was conjectured that nodal domains of random wave functions are adequately described by critical percolation theory. In this paper we strengthen this conjecture in two respects. First, we show that, though wave function correlations decay slowly, a careful use of Harris' criterion confirms that these correlations are unessential and nodal domains of random wave functions belong to the same universality class as non critical percolation. Second, we argue that level domains of random wave functions are described by the non-critical percolation model.

2020 ISSCC Tutorials
Abstract: System behavior and performance of power management strongly depend on the implementation at the circuit level. This tutorial covers the design of DC-DC converter building blocks such as power switches, gate drivers and their supply, level shifters and error amplifiers, as well as control-loop and current-sensing techniques. Circuits for diagnostics and protection will also be addressed. Increasing switching frequency scales down passive components, but poses a challenge for the design of timing-critical circuits. The tutorial will highlight trade-offs between speed, efficiency, complexity, voltage and current capabilities, etc.

description: In this fourth paper in a series, we present a model of the remarkable temporal and azimuthal variability of the Io plasma torus observed during the Cassini encounter with Jupiter. Over a period of three months, the Cassini Ultraviolet Imaging Spectrograph (UVIS) observed a dramatic variation in the average torus composition. Superimposed on this long-term variation, is a 10.07-hour periodicity caused by an azimuthal variation in plasma composition subcorotating relative to System III longitude. Quite surprisingly, the amplitude of the azimuthal variation appears to be modulated at the beat frequency between the System III period and the observed 10.07-hour period. Previously, we have successfully modeled the months-long compositional change by supposing a factor of three increase in the amount of material supplied to Io's extended neutral clouds. Here, we extend our torus chemistry model to include an azimuthal dimension. We postulate the existence of two azimuthal variations in the number of super-thermal electrons in the torus: a primary variation that subcorotates with a period of 10.07 hours and a secondary variation that remains fixed in System III longitude. Using these two hot electron variations, our model can reproduce the observed temporal and azimuthal variations observed by Cassini UVIS.

A phase-locked loop (PLL) is a key building block in both wireless and wireline communications. For wireless systems, the DS PLL-based synthesizer plays a critical role in modern transceivers not only as a local oscillator but also as a phase modulator with direct digital modulation. As to wireline systems, low-jitter clock generation and versatile clock-and-data recovery circuits are critical in high data-rate I/O links. However, diversified PLL architectures with different tradeoffs make it difficult for circuit designers to choose the right design solution for various applications. This presentation discusses PLL architectures and application aspects with key design tradeoffs.
Studies on thiarubrine, a naturally occurring disulfide polyine

description: Chemical and biological aspects of thiarubrine, a highly antifungal dithiacyclohexadiene polyine, were investigated. A tissue culture system for the production of thiarubrines was developed by culturing hairy roots of Chaenactis douglasii induced by Agrobacterium rhizogenes strain TR7. One culture line accumulated two times the levels of thiarubrines of nontransformed control root cultures, while maintaining rapid growth. The combination of fast growth and high thiarubrine accumulation could not be duplicated in controls by adding exogenous NAA to the culture medium. Hairy root cultures also produced less thiarubrine B relative to thiarubrine A compared to controls. Thiarubrine synthesis appears to be closely correlated with degree of tissue differentiation; it is suggested that it may be more practical to improve the growth rate of thiarubrine-producing root cultures by transformation rather than seek to induce synthesis in fast-growing suspension cultures. The biosynthetic relation between thiarubrines and the always co-occurring thiophenes was investigated by performing ³⁵S tracer experiments with C. douglasii hairy root cultures. It is possible that the thiophenes are not actively synthesized by the roots but rather are products of thiarubrine decomposition resulting from the extraction procedures and other manipulations of the cultures. The in vitro conversion of thiarubrine to thiophene can be induced by light, heat and other agents. No turnover of thiarubrines could be detected in the cultures in late logarithmic or stationary phases of the growth cycle. I Thiarubrines show strong light-independent antibacterial and antifungal activity. The mechanism of action of thiarubrine against E. coli and S. cerevisiae was investigated using comparative disk bioassays. A very similiar polyine from Rudbeckia hirta was as active as thiarubrine in the dark, indicating the central role of the disulfide ring in toxicity of the compounds. Visible light enhanced this activity suggesting that decomposition of the disulfide ring is important for its antibiotic effects. The photodegradation product, a thiophene, is phototoxic, probably via both type I and type II photosensitization mechanisms. The root culture extracts of Rudbeckia hirta yielded a new isomer of a known dithiacyclohexadiene polyine. MS and NMR analyses confirmed the cis configuration of this isomer.

description: Multi-input multi-output orthogonal frequency division multiplexing (MIMO OFDM) is a key technology for mobile communication systems. However, due to the issue of high peak-to-average power ratio (PAPR), the OFDM symbols may suffer from nonlinear distortions of the power amplifier (PA) at the transmitters, which degrades the channel estimation and detection performances of the receivers. To mitigate the clipping distortions at the receivers end, we leverage deep learning (DL) and devise a DL based receiver which is aided by the traditional least square (LS) channel estimation and the zero-forcing (ZF) equalization models. Moreover, a data driven DL based receiver without explicit channel estimation is proposed and combined with the model aided DL based receiver to further improve the performance. Simulation results showcase that the proposed model aided DL based receiver has superior performance of bit error rate and has robustness over different levels of clipping distortions.

Abstract: Most amplifier designers spend at least as much or more effort assuring stability under all operating conditions with proper frequency compensation than on other amplifier features. This tutorial will revisit the basics of frequency compensation such as Miller, parallel, nested-Miller and feed-forward compensation and compare them in terms of power efficiency and load-drive capabilities. We will look into the loading effects of subsequent stages, common design traps and round up with a case study of recently published amplifiers.

description: Dynamic response of the one-dimensional viscoelastic rod of finite length, that has one end fixed and the other subject to prescribed either displacement or stress, is analyzed by the analytical means of Laplace transform, yielding the displacement and stress of an arbitrary rod's point as a convolution of the boundary forcing and solution kernel. Thermodynamically consistent Burgers models are adopted as the constitutive equations describing mechanical properties of the rod. Short-time asymptotics implies the finite wave propagation speed in the case of the second class models, contrary to the case of the first class models. Moreover, Burgers model of the first class yield quite classical shapes of displacement and stress time profiles resulting from the boundary forcing assumed as the Heaviside function, while model of the second class yield responses that resemble to the sequence of excitation and relaxation processes.

This presentation deals with PLL fundamentals and their role in wireless systems. Following a brief overview of basic PLL operation, we study its imperfections and their impact on the performance. This culminates in the study of phase noise and its formulation in PLLs. We then introduce modeling methods for fast and relatively accurate PLL simulation. Finally, we study specific issues related to RF synthesis and look at the new trends in synthesis design.

description: In the vortex core of slightly overdoped Bi2Sr2CaCu2Ox, the electron-like and hole-like states have been found to exhibit spatial modulations in anti-phase with each other along the Cu-O bonding direction. Some kind of one-dimensionality has been observed in the vortex core, and it is more clearly seen in differential conductance maps at lower biases below +-9 mV.

description: The predation risk of many aquatic taxa is dominated by visually searching predators, commonly a function of ambient light. Several studies propose that changes in visual predation will become a major climate-change impact on polar marine ecosystems. The high Arctic experiences extreme seasonality in the light environment, from 24-h light to 24-h darkness, and therefore provides a natural laboratory for studying light and predation risk over diel to seasonal timescales. Here, we show that zooplankton (observed using acoustics) in an Arctic fjord position themselves vertically in relation to light. A single isolume (depth-varying line of constant light intensity, the value of which is set at the lower limit of photobehaviour reponses of Calanus spp. and krill.) forms a ceiling on zooplankton distribution. The vertical distribution is structured by light across timescales, from the deepening of zooplankton populations at midday as the sun rises in spring, to the depth to which zooplankton ascend to feed during diel vertical migration. These results suggest that zooplankton might already follow a foraging strategy that will keep visual predation risk roughly constant under changing light conditions, such as those caused by the reduction of sea ice, but likely with energetic costs such as lost feeding opportunities due to altered habitat use.

Abstract: NAND Flash and eFlash have been the workhorse of memory hierarchy for standalone storage and embedded non-volatile memories (NVMs), respectively. But with the ever increasing need for memory capacity and bandwidth, due to new applications in graphics, AI and IoT, device and circuit designers have been heavily investigating alternative memories to fill the need. When it comes storage, there is a big gap between DRAM and NAND in terms of density and speed, which could justify a new memory type. When it comes to NVM, growing IoT requires better performance and more power efficient NVM than eFlash, which can be scaled to 1xnm technologies. This tutorial will talk about the basic characteristics, circuits and system designs for emerging non-volatile memories such as MRAM, RRAM, and PRAM. The tutorial will present the details of MRAM and RRAM, as well as a comparison of these memory devices, and the applications they target.
