摘要: 本文给出了适合于线性有源网络优化设计的一种有效方法.在电路优化设计中,计算费用主要取决于目标函数计算。通常情况下,一个线性网络的模拟要求解维数较高的线性方程。电路优化设计中一个很重要的特点是独立可调设计参数的数目较小,依据线性网络的性质,将其表征为一个多端口网络,在优化之前建立混合参数矩阵,每次目标函数计算中仅需求解一个维数和设计参数数目相同的方程,因而非常省时。

Abstract: An efficient method for the optimization of linear network is presented. The computation cost in circuit optimization mainly depends on the simulation of network. In general, the simulation of a linear network needs to solve high dimension linear equations. An important characteristic in circuit optimization is that the number of independently tunable parameters is small. In term of the property of linear networks, the circuit is described by a multiport network in present method, and the hybrid matrix is established. The dimension of the equations to be soloved is the same as the number of optimization parameters in objective function evalutions, so this method is very efficient. -
