摘要
本文根据理想运算放大器的原始定义和对偶原理,指出将理想运算放大器的特性描述(归纳)为"虚短虚断"存在问题,提出可用"假短真断(虚短实断)"描述(归纳)理想运算放大器特性;对与理想运算放大器和实际运算放大器特性描述相关的问题进行了分析和讨论,给出了一些意见和建议。
According to the original definition of the ideal op amp and the duality principle , this paper indicates it is inappropriate to describe the characteristics of the ideal op-amp as ＂virtual short and virtual open＂, and it is ap- propriate to describe the characteristics of ideal op-amp as ＂false short and true open （virtual short and real open） ＂. The problems related with the characteristic description of the ideal op-amp and the actual op-amp are an- alyzed and discussed, some opinions and suggestions are given in the paper.
