摘　　要：在测试负反馈放大器性能时由于受到传统实验教学方式和实验条件的限制,实验结果不能准确反映负反馈对放大器性能的影响。而利用Multisim仿真技术,通过分别对无反馈的基本放大器和带反馈放大器各项性能指标的测试,研究并提出了电压串联负反馈放大器的Multisim电路仿真分析方法。实践证明,在教学中引入Multisim仿真技术,对分析、调试电路具有很好的辅助作用,是开放性实验教学改革的一种新途径。In the test of negative feedback amplifier performance due to the traditional experiment teaching mode and the limitation of experimental conditions, the experimental results can not accurately reflect the effects of negative feedback amplifier performance. While using the Muhisim simulation tech- nology, based on the feedback of basic amplifier and feedback amplifier tests of various performance indicators, research and put forward the series voltage negative feedback amplifier Multisim circuit sim- ulation analysis method. Practice has proved that introduces Multisim simulation technology in the teaching, the circuit analysis, debugging has the very good auxiliary function, is a new way of open ex- perimental teaching reform.
