Abstract
In this paper, we present a new technique, based on a continuation method, for oscillator analysis using harmonic balance. With the use of Krylov subs pace iterative linear solvers, harmonic balance has become a very powerful method for the analysis of general nonlinear circuits in the frequency doma in. However, application of the harmonic balance method to the oscillator p roblem has been difficult. The strong dependence of the oscillator behavior on frequency, and the dependence of the frequency of oscillation on the ci rcuit waveforms result in a very small region of convergence for harmonic b alance. The main contribution of this paper is a robust and efficient conti nuation method to obtain global convergence. (C) 2000 Published by Elsevier Science S.A. All rights reserved.
