A wavelet balance approach for steady-state analysis of nonlinear circuits

In this paper, a novel wavelet balance method is proposed for steady-state analysis of nonlinear circuits. The proposed method presents several merits compared with those conventional frequency domain techniques. First, it has a high convergence rate. Second, it works in time domain so that many critical problems in frequency domain can be handled efficiently. Third, an adaptive scheme exists to automatically select the wavelet basis functions needed at a given accuracy.
