摘　　要：利用ＳＰＩＣＥ（集成电路通用模拟程序）的多项式受控源可以实现多种复杂的非线性数学方程。本文给出了均方根值和绝对值的ＳＰＩＣＥ宏模型，将由几个受控源及电容、二极管简单模型构成的宏模型插入电路系统中，代替一级复杂的电路或一个功能模块，从而可提高分析精度，减少分析时间，克服不收敛问题，简化程序设计。这种宏模型也可以作为验证电路功能的一种手段，特别是在电路需要多次调用这一功能模块时，更显示出其优越性。The SPICE2(simulation program with integrated circuit emphasis)polyno-mial controlled source can be used to realize a number of nonlinear mathemat-ical functions.In this paper, both root mean square value and absolute value macromodels are presented.The macromodels that is composed of controlled sources, capacitances and diodes can be uesd in circuit to replace the complex subcircuit or a functional module,Using macromodels can reduce simulation time,improve analysis accuracy,overcome non-convergence problem and simplify program design,This kind of macromodel also can be used to verify the circuit function. In particular, when a function module is used many times,advantage of using a macromodel is obvious.
