Abstract :
A predictor-corrector tracing curve algorithm for analysis of nonlinear circuits is presented. In order to trace the curves having sharp turning points efficiently, the authors introduce a norm |Σ dxi/ds| as the parameter to control the tracing step size. In addition, the Hermite polynomial is used for extrapolation in the predictor stage, and the Brown iteration method is used to solve the system of equations in the corrector stage. The numerical examples show that computational efficiency is greatly improved, so that this algorithm can be used for DC analysis of nonlinear circuits efficiently
