| 摘 要： | 本文指出了文献1]中不正确的分析结果,并讨论了文献1]产生错误的原因.在电压跟随器电路中引入了负反馈,电路能够正确工作,如果将其中的负反馈改为正反馈,电路将工作在饱和区,达不到电压跟随的目的,此时的电路实际上变成了一种史密特(Schmitt)触发器.须知,电路仿真软件的分析结果是对电路实际运行结果的一种近似,并非在所有的情况下都与实际电路结果一致.

| Abstract: | This paper points out what and why of the incorrect analysis for voltage followers in reference 1]. Negative feedback is introduced in the voltage follower whose output voltage can follow its input voltage. It will work in saturated region if the negative feedback is exchanged into positive feedback and then the circuit is not a voltage follower, but changed into a Schmitt trigger actually. It is noted that the results produced from the circuit simulation software reflect the operation of actual circuits approximately and can not consistent with each other in all cases. |
