摘要
从振荡器在Proteus软件中仿真时不易起振的现象入手,分析得出结论是因振荡器缺乏初始扰动信号而引起的。为此,给出了几种在电源中人为加入扰动信号的方法,并以文氏桥式振荡器为例进行了电路仿真。仿真结果表明,在电源中人为地加入波动分量的方法可以解决在Proteus仿真中振荡器的起振问题。
From the phenomenon of oscillator's difficultly starting oscillation in Proteus simulation,the paper makes an analysis and concludes that it is due to the oscillator's lack of initial disturbance signals.A few methods of adding disturbance signals to power supply are introduced and the Wien Bridge Oscillator is taken as an example to simulate in Proteus.The results show that the method of adding disturbance signals to power supply can solve the oscillation-starting problem in Proteus simulation of oscillator.
