摘　　要：提出的一种新的通用非线性时域运算放大器宏模型是为了集成电路运算放大器的时域模拟。它与早先报道的非线性时域运算放大器宏模型有两点不同。①通过使用压控开关和非线性受控源来模拟运算放大器的非线性特性。②该宏模型在PSpice环境下生成并运行 ,主要用于D/A集成电路的仿真 ,且便于使用。In this paper, we present a new general purpose nonlinear macromodel for simulation of integrated circuit operational amplifiers(op amps). We mention two main differences between this macromodel and those previously reported in the nonlinear for time domain. First, all the nonlinearities of op amps are simulated using votage control switch elements and nonlinearites contral source elements. Second, this macromadel are producted and operated using Pspice softwear. The main application of this macromodel is for the simulation of the analogic part of a combined D/A intergrated circuit, and it is easy to application.
