A novel wavelet method for noise analysis of nonlinear circuits

ABSTRACT

In this paper, a novel wavelet method is proposed for noise analysis of nonlinear circuits. Compared with the existing algorithms capable of accessing circuit performance in the present of noise, the proposed method presents several merits. First, it fully accounts for nonlinearities. Second, it can handle signals with continuous frequency spectra. Third, by taking advantage of the properties of the wavelet bases, such as local compactness and multi-resolution, it holds high simulation speed and high accuracy. Furthermore, an adaptive scheme exists to automatically select the wavelet basis functions for a desired accuracy. All these merits make the novel wavelet method outperforms its previous techniques.
