摘　　要：由二极管和电容构成的基本箝位电路是华科版模拟电子技术课程中的基本电路,教科书中分析较为简单。从二极管恒压降模型和指数函数模型出发结合电容伏安关系,详细完整的分析该箝位电路,所用方法有助于增强学生对于二极管伏安特性、电容伏安特性和高等数学中导数基本概念的理解。The basic clamper circuit composing of a diode and a capacitor is a fundamental circuit in the analog circuit textbook published by Huazhong University of Science and Technology.The analysis in the textbook is relatively simple.In this paper,the clamper circuit is analyzed in detail based on the voltage-current relationship of a diode and that of a capacitor.Then,based on the exponential function model of a diode,the mathematical definition of the derivative and the voltage-current relationship of a capacitor,the clamper circuit is analyzed using an iterative numerical method.The proposed methods are instrumental to the students’ understanding of the diode and capacitor as well as the definition of derivative.
