線性有源網(wǎng)絡(luò)的高效模擬和優(yōu)化設(shè)計
EFFICIENT SIMULATION AND OPTIMIZATION OF LINEAR ACTIVE NETWORKS

摘要: 本文給出了適合于線性有源網(wǎng)絡(luò)優(yōu)化設(shè)計的一種有效方法.在電路優(yōu)化設(shè)計中,計算費用主要取決于目標(biāo)函數(shù)計算。通常情況下,一個線性網(wǎng)絡(luò)的模擬要求解維數(shù)較高的線性方程。電路優(yōu)化設(shè)計中一個很重要的特點是獨立可調(diào)設(shè)計參數(shù)的數(shù)目較小,依據(jù)線性網(wǎng)絡(luò)的性質(zhì),將其表征為一個多端口網(wǎng)絡(luò),在優(yōu)化之前建立混合參數(shù)矩陣,每次目標(biāo)函數(shù)計算中僅需求解一個維數(shù)和設(shè)計參數(shù)數(shù)目相同的方程,因而非常省時。

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. -
