Use of SPICE in analogue computation and simulation of systems consisting of circuit components and transfer functions

Abstract

Based on the SPICE2G6 program, methods of generating analogue functions, such as integration, simple poles and zeros, complex poles and zeros, are introduced. These functions are used for the modelling and simulation of nonlinear and time-dependent differential equations. Mixed simulation of circuit components and analogue transfer functions is also studied. Mixed simulation allows the circuit designer to study critical parts of a complex circuit in detail, down to circuit component levels, while representing other parts by transfer functions to speed up the simulation.
