1.引言在实际电路中,广泛应用着各种非线性元件、器件,尤其是各种电子元、器件。因此,非线性电路分析在整个电路分析中是十分重要的。直流分析又是非线性电路分析(包括直流分析、瞬态分析、灵敏度分析等)的基础。非线性电路的直流分析有多种方法,如图解法、估算法、模型法及分段线性法等。目前,在电子技术基础教材中,一般只介绍图解法和估算法。图解法是分析非线性电路最常用的方
1. Introduction In the actual circuit, widely used in a variety of nonlinear components, devices, especially a variety of electronic components, devices. Therefore, non-linear circuit analysis in the entire circuit analysis is very important. DC analysis is the basis of nonlinear circuit analysis (including DC analysis, transient analysis, sensitivity analysis, etc.). There are many methods of DC analysis of nonlinear circuits, such as graphic method, estimation method, model method and piecewise linear method. At present, in the basic textbook of electronic technology, generally only the graphic method and the estimation method are introduced. Graphical analysis is the most commonly used method of analyzing nonlinear circuits
