一种学习放大电路和反馈基本原理的新方法

摘要

In learning course of Fundamentals of Analogue Circuits, the amplifiers and feedback are difficult . The conventional method is analysis, that is for a given amplifier and feedback, the teacher illustrates the function for every elements and the type of the feedback. In this paper, the author presents a new teaching method from the view of designing amplifiers and designing feedback for an amplifier. Starting from a transistor , a required circuit is achieved by adding the elements one by one. The new designing method is helpful for the students.%在“模拟电子技术基础”课程中，对放大电路和反馈基本原理的理解是难点。常规的授课思路是分析的学习方法，给定一个放大电路和反馈，然后分析各元件的作用和反馈的类型。本文介绍一种新的学习方法，从三极管开始逐个增加元件，直至一个满足要求的电路，这种基于设计的新方法有利于学生的理解。
