摘　　要：模拟电子线路是一门理论性和实践性很强的专业基础课 ,也是一门比较难学的课程 负反馈是模拟电子线路中一个重要内容 ,它在电子技术中占有重要的地位 由于负反馈的概念抽象、复杂 ,许多学生感到难以理解和掌握 ,负反馈电路的量纲更难以记忆 文中主要介绍负反馈电路类型的判断 ,同时分析负反馈电路参数的含义和量纲 。The technology of anologue electronic circuit is a theoretical and practical specialized basic course,which is a more difficult one.Negative feedback is an important part of anologue electronic circuit and plays a very important role in electronic technology.Due to the fact that the concept of negative feedback is very abstract and complicated,many students feel that it is very difficult for them to understand and master it.Furthemore,the dimensions of negative feedback are difficult to be memorized.This article mainly tells us how to judge the categories of the negative feedback.The meaning and dimension of the negative feedback parameters are also analysed so that students get a deeper understanding of the negative feedback.

关 键 词：负反馈 电路参数 量纲分析 类型判别 模拟电子线路 反馈电路
