摘　　要：负反馈是模拟电子课程中的重要概念,内容抽象繁杂,与基本放大电路关系密切,经常造成学生理解混乱。本文以电压串联负反馈电路为例,利用Multisim软件仿真功能,直观的计算负反馈电路的各性能指标和输入输出波形,将较为抽象的理论知识具体化,结果表明,加强了学生对负反馈作用的理解,教学效果明显提高。Negative feedback is an important concept in analog electronic courses with abstract content,and closely related to the basic amplification circuit,which often causes confusion for students.In this paper,taking the voltage series negative feedback for example,Using Multisim software circuit simulation function,We calculate intuitively negative feedback circuit performance indicators of input and output waveforms,enalbe the abstract theoretical knowledge to become concrete,which helps students understand the role of negative feedback.

关 键 词：晶体管 模拟 负反馈 MULTISIM 电路性能
