An Effective Implementation of the Nonlinear Homotopy Method for MOS Transistor Circuits

Abstract

Recently, an efficient homotopy method termed the nonlinear homotopy method (NLH) has been proposed for finding DC operating points of MOS transistor circuits. This method is not only efficient but also globally convergent. However, the programming of sophisticated homotopy methods is often difficult for non-experts or beginners. In this paper, an effective method for implementing the MOS NLH method on SPICE is proposed. By this method, we can implement the MOS NLH method from a good initial solution with various efficient techniques and without programming.
