description: In this work, the study of TIAs with different parameters of the input signal was carried out. We used the means of automated development, applied numerical methods to solve the problems based on the software Micro-CAP 12. Methods of search and analysis of information from the following sources and databases https://library.spbstu.ru/ru/erm/ have been applied. Dependence of circuit characteristics on element ratings has been established. Formulas for theoretical estimation of input impedance and bandwidth are presented. The influence of deviation of element ratings on circuit characteristics is evaluated. The problem of circuits going out of operating mode when deviating the nominal values of elements is revealed. As a possible solution to this problem the resistors were replaced with pseudo-resistors. A comparative analysis of circuits with ordinary and pseudo resistors was made. It was found that this replacement leads to improvement of the majority of circuit characteristics. In addition, the problem of circuits going out of operating mode when deviating the nominal values of elements was solved. Also the scatter of characteristics when deviating the nominal values of elements was reduced. Among all the circuits identified two circuits TIAs, which on the totality of parameters showed the best result compared to other circuits.
