目前各种文献中介绍的图解分析法只适用于简单电路,分析复杂电路均采用解析法。本文采用新的图解方法分析复杂电路的静态工况,首先利用图解法求额定负载下的静态β,然后用作图法求电路的I_(BQ)、I_(CQ)、V_(CKQ),并对解析和图解两种方法进行了误差分析。文章也以差动放大器为例作了对复杂电路进行动态图解分析的初步尝试。
At present, the graphical analysis methods introduced in various literatures are only applicable to simple circuits, and analytical methods are used to analyze complex circuits. In this paper, a new graphical method is used to analyze the static operating conditions of complex circuits. First, the static β under rated load is obtained by the graphic method, and then used to obtain the I_ (BQ), I_ (CQ) and V_ (CK_Q) Error analysis is made on the two methods of analysis and illustration. The article also made a preliminary attempt of dynamic graphical analysis of complex circuits by taking differential amplifiers as an example.
