Nonlinear macromodels for time-domain simulation of analog-discrete circuits

Macromodels of nonideal analog-discrete (SC and SI) circuits are proposed in this report, which take into consideration the nonlinear characteristics of the building blocks. Linearized computer models in the discrete-time domain are worked out, which provide the opportunity of using the possibilities of the general purpose analysis programs to investigate analog discrete circuits. The application of the developed macromodels is illustrated by a numerical example. The results are obtained using the PSpice program
