摘要
在传输线网络瞬态响应灵敏度分析之中,提出了一种基于NILT的新的分析方法.该方法将传输线及其效应连同电子元器件及单元电路作为一个整体,根据传输线在电路中的拓扑关系,将传输线网络瞬态响应灵敏度分析问题转化为求解传输线网络瞬态响应问题,以及传输线ABCD矩阵对电路参数的偏导数问题.通过将ABCD矩阵进行级数展开,极大地简化了ABCD矩阵对电路参数偏导数的计算以及传输线网络瞬态响应灵敏度的分析.本文方法不需要对耦合传输线进行解耦,具有简单、精确、高效等特点,算例结果表明了本文方法的有效性.
Abstract
A novel method based on NILT is presented to analyze the sensitivity of transient response of the networks containing transmission lines.In this method,transmission lines,circuit and its components are taken into account as awhole.According to the topology of the transmission lines in the circuit,the sensitivity of transient response of the circuit can be derived by solving the transient response of the circuit and the partial derivative equation of the ABCD matrix of the transmission lines with respect to the parameters of the circuit.By conducting a series expansion of the parameter matrix,the problem can be simplified dramatically.Without decoupling calculation of the coupled transmission lines,this method is simple and accurate.The example given shows the effectiveness of the method.
