利用“交叉类比”学习法掌握基本放大电路特性

Use Such Learning Method as "Cross Analogy" to Master Basic Amplifying Circuit Characteristics

在模拟电子技术课程的教学中,分立器件构成的基本放大电路的静态和动态特性分析,是掌握放大电路工作原理中的一个基本知识点。作者经过多年的教学探索和实践,通过"交叉类比"的学习方法,能有效地帮助学生更快更深入地理解由各类分立器件构成的不同组态的放大电路特性。本文以晶体三极管和场效应管构成的基本放大电路特性的授课为例,从不同的电路拓扑入手,分析了"交叉类比"在授课中的应用。几年来的教学效果评估显示,采用这种授课方式可以起到事半功倍的效果。

In analog electronic technology curriculum teaching, the static and dynamic characteristic analysis for the division of the basic amplifying circuit components is a basic point to master the amplifier circuit principle.After years of teaching exploration and practice,the paper,through the learning method of ＂cross analogy＂,effectively helps students have a better and faster understanding of the amplifier circuit characteristics consisted of all kinds of division of the different components configuration.
