Study on Simulation of Gate Circuit Self-excited Multivibrator

Abstract

Simulation in circuit design is increasingly used in recent years, because it can not only optimize design, reduce experiment consumption, but also improve design efficiency. However, when gate circuit self-excited multivibrator is simulated using EWB. The result of simulation experiment is wrong and is inconsistent with the one of real circuit experiment at all. Why dose this phenomenon happen? In this paper, a simulation experiment was made and the reason of wrong simulation experiment result was analyzed. At last, a solution method of simulation experiment was pointed out. This simulation experiment shows, in some special condition, little things can lead to a large difference.
