摘　　要：差分放大电路是模拟电子技术学习过程中的一个重点和难点,若学生未能充分理解其工作原理就进行实际电路的测试,实验效果难以保证。借助计算机仿真技术,在测试实际电路之前让学生先对待测电路有一定的了解,可以很好地解决这个问题。将Multisim仿真技术引入差分放大电路实验,对其基本电路结构进行仿真和测试,可以帮助学生理解差分放大电路的工作原理。实践证明,Multisim仿真有助于学生实验操作的顺利进行和实验数据的正确分析。Differential amplifier circuit is one of the key and difficult points in the study of analog electronics technology.If the student cannot fully understand the working principle before the actual circuit test,the effect of the experiment is difficult to be ensured.With the help of computer simulation technology,the student can have some understanding of the circuit which will be tested,so the problem can be well solved.In this paper,Multisim simulation technology is introduced into the differential amplifying circuit experiment,and the basic circuit structure is simulated and tested,which can help the student understand the working principle of differential amplifying circuit.Practice has proved that Multisim simulation can help the student to carry out the experimental operation smoothly and analyze the experimental data correctly.
