Using Mathematical Modeling for Multiparametric Analysis of Electronic Circuits With a Linear Active Device

It is proposed to use matrix methods for mathematical modeling of the operation of electronic analog linear devices. They allow using computational tools to obtain results with high calculation speed and acceptable accuracy. For example, a scheme of an active second-order electronic filter based on an operational amplifier is proposed. A multiparametric analysis of the transfer function based on the primary parameters of the electronic circuit is proposed. The proposed method for analyzing linear active electronic circuits based on the conduction matrix can significantly reduce the calculation time and significantly simplify the forms of writing analytical expressions. The calculation results are com-pared with the results obtained in a specialized program for modeling electronic circuits OrCAD PSpice. For example, the transfer function is analyzed according to the following parameters: sensi-tivity, statistical synthesis, optimization of tolerances
