摘要
本文提出了一种适用于较大规模模拟电路行为级的建模方法.首先,将任何一个模拟电路等效为由电源(Source)、放大器(Amplifier,也可以看作为一个有增益的滤波器)、开关(Switch)、阻抗(Impedance)、等基本单元组成的网络.本文把这种网络称为模拟电路的SASI结构.其次,根据此种划分下的网络结构和Hammerstein模型结构的等价性,基于Hammerstein模型对模拟电路的宏模块进行建模.最后,采用硬件描述语言(Verilog-A,VHDL-AMS等)来描述这种SASI结构,从而完成整个模拟电路的行为级建模.采用该方法建立的模拟电路行为模型是一个参数化非线性动态模型,有利于模拟电路系统级整体设计.以采用"Top-Down"法设计红外遥控接收器、建立其行为模型为例,结果表明了该建模方法的有效性.
A methodology to build a behavioral model for large scale analog circuits is presented in the paper.Any analog circuit can be equivalently described by a network consisting of Sources,Amplifier（amplifier can be considered as a virtual filter with gains）,Switchers and Impedance.This network is defined as analog circuits＇ SASI structure in the paper.Due to the equivalency between this abstracted network and Hammerstein model,macro behaviors of analog circuits can be modeled based on Hammerstein method.Then,those macro behavior models can be described by using the standard HDL（Verilog-A,VHDL-AMS,and so on）accordingly.This Top-Down methodology is validated using the in-house designed Infrared Remote Control Receiver as an example.
