摘要

谐波平衡法是非线性电路中稳态分析的一种有效的方法。作为这种方法的重要组成部分，时域和频域之间的变换与反变换需要反复地进行．因此，其算法的好坏，直接关系到谐波平衡法的效率，本文针对这一问题，提出一种新的计算非线性元件频谱的方法，根据非线性函数本身的性质，充分利用稳态响应中各频率分量已知等信息，直接获得非线性元件的响应，从而达到了快速、准确的目的。

Abstract

The Harmonic Balance method is an efficient method in steady state analysis of nonlinear circuits.As a very important part

algorithms of spectra calculation should be selected carefully.In this paper

we apply a new algorithm to calculate the spectra of nonlinear elements

which fully utilizes the nonlinear functions’characteristics and the known frequency components in the steady-state response.Without any sampling

we get the spectra directly.The time and memory have been greatly reduced.
