摘　　要：模拟电路是一门较难学习的专业基础课程,学好模拟电路对后续课程的学习至关重要。放大电路是模拟电路的基础,共发射极基本放大电路是学生接触的第一个重要的放大电路。本文阐述了在教学中引入仿真使学生对共发射极基本放大电路的功能有直观的认识。通过修改仿真电路中某些元件的参数,使学生初步意识到共发射极基本放大电路的放大倍数该如何调整,从而自然过渡到对放大电路理论的分析学习。强调理论学习结合仿真,教师易于操作,学生易于理解与掌握。Analog circuit is a professional basic course which is difficult to learn.It is very important to learn analog circuit well.Amplifier circuit is the basis of analog circuit,common emitter basic amplifier circuit is the first important amplifier circuit that students contact.In this paper,the introduction of simulation in teaching,so that students have an intuitive understanding of the function of common emitter basic amplifier circuit.By modifying the parameters of some components in the simulation circuit,the students can initially realize how to adjust the amplification factor of the common emitter basic amplifier circuit,so as to naturally transition to the analysis and learning of the amplification circuit theory.It emphasizes that theoretical learning combined with simulation makes it easy for teachers to operate and students to understand and master.
