目前用集成运算放大器构成的电子线路日渐增多,它已渗透到各类仪器、仪表、自动化工程等领域。对这些电路进行近似分析,迅速方便地得到工程上所需结果乃是电路设计和使用人员尤为关注的问题。最初,提出“虚地”法,由于它的局限性在某些电路中不能使用。尔后,引出“零子”、“任意子”两个假想的理想元件,先画出等效电

At present, the electronic circuits formed by integrated operational amplifiers are increasing in number and have penetrated into various fields such as instruments, meters, automation engineering and the like. An approximate analysis of these circuits and the prompt and easy availability of the desired results are of particular concern to circuit designers and users. Originally, the “false ground” method was proposed and could not be used in some circuits due to its limitations. Later, leads to “zero child”, “arbitrary child” two hypothetical ideal components, first draw the equivalent
