Computing large-change sensitivity of periodic responses of nonlinear circuits using reduction techniques

Abstract

This work presents a new technique for computing large-change sensitivity (LCS) of steady-state operating point in nonlinear circuits. The basic idea underlying the algorithm is the construction of a reduced system of nonlinear equations that preserves the derivatives of steady-state response with respect to the desired network parameters. Large change variations are then obtained by solving the reduced systems instead of the original one.
