摘　　要：模拟电子技术课程是一门偏向于应用类的电子专业基础课,教学内容较多且难度较大。随着Multisim软件的应用,很好地弥补了传统实验课程的不足,教师可以在讲课过程中实时演示实验。因此任课教师需要设计基于Multisim的实验内容来满足教学要求。以负反馈放大电路为例,阐述了负反馈放大电路动态参数的仿真测量,并验证了负反馈对动态参数性能的影响。Analog electronic technology is an electronic basic application course.There are many teaching contents,and it is difficult.With the application of Multisim software,it can make up for the shortcomings of traditional experimental courses.Teachers can demonstrate experiments in real time during the teaching process.Therefore,teachers need to design the experimental content based on Multisim to meet the teaching requirements.Taking“negative feedback amplifier”as an example,this paper expounds the simulation measurement of dynamic parameters of negative feedback amplifier,and verifies the influence of negative feedback on the performance of dynamic parameters.
