1.和普通RC辰蕩器比較 在普通RC振蕩器中,起振的相移和振幅条件同时取决子RC反饋网路,RC数值的变化,引起振蕩頻率和反馈系数的同时改变,如果不加稳幅装置,要维持振蕩是較困难的。稳幅装置通常是对振蕩的平均功率起反应的一种非线性元件。当頻率降低时,这种装置的时間常数很不容易选擇恰当。因为此时間常数若不够大,和極低頒振蕩的周期可 1. Compared with ordinary RC oscillator In ordinary RC oscillator, the phase shift and amplitude of the starting condition depend on the changes of the sub-RC feedback network and the RC value at the same time, causing the oscillation frequency and the feedback coefficient to change at the same time. If not Steady amplitude device, to maintain the oscillation is more difficult. The stabilizer is usually a non-linear element that reacts to the average power of the oscillations. When the frequency is reduced, the time constant of this device is not easy to choose properly. Because if this time constant is not big enough, and very low oscillation cycle can be
