“模拟电子技术”负反馈章节内容的教学改革与实践

The Teaching Reform and Practice of Negative Feedback Section＇s Content in Analog Electronic Technology

将传统的负反馈章节的内容进行大的改革，从运放电路人手讲解负反馈的概念，以及反馈的四种类型。最后推广到分立元件组成的放大电路的反馈类型判断。这种方法简单明了，容易判断，对于理解反馈的作用有很大的帮助。

The reforms are largely done to the traditional negative feedback sections , It explains the concept of negative feedback, and four types of feedback by starting from the integrated operational amplifier circuit. Finally it is promoted to judge discrete components composition of the feedback type of amplifier circuit. This method is simple and easy to judge, for understanding the role of feedback very helpful.
