A Multisim Simulation Assistant new Experiment Method for Single Stage RC Coupled Transistor Amplifier

单极阻容耦合放大器是电子技术课程必做的基础实验。本文首先针对验证型实验,采用Multisim10.0电路仿真软件测试和分析电路的各项指标,仿真结果与实际电路测试结果基本一致。同时,针对设计型实验,根据设计指标要求,结合传统的理论推导和Multisim,系统地设计了单极阻容耦合放大器电路,经过仿真修正和实际电路测试,完全达到设计要求。

It is the basic experiment for the single stage RC coupled transistor amplifier in electronics courses. In this article, the circuit simulation tool Multisim10.0 is introduced. First, in the confirming experiment, more test instruments are used in simulation than in lab, as a consequence, the tests are more thoroughly and the analysis for the test results are more intensive. The simulation results are basically consistent with the real test in lab. Second, the simulation is also helpful in designing experiment. In this article, the traditional deducing method is used before the simulation which corrects the design error afterwards. The tests in lab passed all requirements.
