In order to understand the applications of Multisim in the actual circuit design and simulation, the integrated operational amplifier is taken as a research object and its simulation analysis is carried out based on Multisim. In allusion to three different connected modes of the integrated operational amplifier, three simulation experiments about the same proportion operation, reverse proportion operation and differential amplification were performed respectively. The results show that they are consistent with the theoretical calculation results. Finally, a solution to the common problems existing in the simulation process is presents, so as to provide the convenience for the researchers in this field.%为了了解Multisim在实际电路设计与仿真中的应用,在此以集成运算放大器为研究对象,基于Multisim对其进行了仿真分析,针对集成运算放大器的三种不同连接方式,分别做了同比例运算、反相比例运算和差分放大等三组仿真实验,实验结果表明其理论计算与仿真结果一致.最后,还提出了解决仿真过程中出现的常见问题的方案,从而为从事该领域研究的工作者提供了一种便利.
