一种确定弱非线性双端口网络模型参数的新方法

A New Method of Model Parameter Extraction for Weakly Nonlinear Two-Port Networks

非线性传输函数模型和非线性电流源模型是利用Volterra级数对非线性动态电路建模的两种形式;本文提出一种确定一类弱非线性双端口网络非线性电流源模型参数的方法,它通过测量网络的端口特性来确定其模型参数;这种方法比测量Volterra核的方法简单方便。

Nonlinear transfer function model and current source model are the two basic types of the nonlinear dynamic circuits modeling by the Volterra-series approach. An approach to determine the model parameters of weakly nonlinear two port networks is proposed in this paper. This method determines the model parameters by measuring the characteristics of nonlinear networks,which is easier and more convenient than that by measuring the Volterra kernels.
