摘要

针对场效应管电路分析中不同元件性能参数不同而导致一些理论计算复杂、繁琐,并且难于理解的情况,通过对N沟道增强型MOS场效应管组成的分压-自偏压共源放大电路的理论研究,利用Multisim仿真软件对电路实际工作情况进行模拟,根据二者结果的对比,研究并提出了分压-自偏压共源放大电路的Multisim电路仿真研究的方法.%Since different components have different performance parameters which may lead to some complex theoretical calculations and situation which is cumbersome and difficult to understand in the analysis of FET circuit, a method of Multisim simulation research for the partial pressure &- self-bias voltage common source amplification circuits is proposed, according to the theoretical study of the partial pressure &. Self-bias voltage common source amplification circuits compbsed of N-channel enhancement mode MOS FET after the simulation of the actual working condition of the circuits by the aid of Multisim simulation software.
