The Implementation of High-Order Single-Step Integration Technique into Circuit Simulator

This paper presents a new integration technique for time-domain simulation of nonlinear electronic circuits. The new technique exploits A -stable single-step integration methods of order 1 up to 4 obtained by applying the Obreshkov formula to charge oriented circuit equations. The predictor-corrector algorithm exploited in the transient analysis for solving the initial value problem is described. The numerical examples of time-domain simulation are given which demonstrate the numerical accuracy and efficiency of the proposed technique.
