description: The aim is to simulate different configurations of pseudo-resistors on the basis of the analysis of existing studies, to reveal the influence on their resistive properties of the length and width of the transistor channel and to derive dependences on the circuit parameters to obtain pseudo-resistors with the required characteristics. As a result of the study, were analyzed different configurations of pseudo-resistors, simulation of them in the Micro-CAP 12 CAD system was carried out, were found and analyzed the dependences of pseudo-resistors characteristics on the geometric dimensions of the transistor channel, on which they are based, and on the parameters of signals in the simplest circuits. Finally, as an example, an approach for selecting a pseudo-resistor with specified parameters for creating a low-pass filter operating in the audio range has been considered. In the course of work, methods of search and analysis of information from the following sources and databases https://library.spbstu.ru/ru/erm/ were applied, means of automated development were used, numerical methods for solving problems based on the software Micro-CAP 12 were applied. The results of this work can be used to understand the algorithm of selection of pseudo-resistors with the necessary parameters.
