摘要
本文讨论了开关电容振荡器(SCO)的起振和幅值稳定问题。提出了SCO的起振和幅值稳定的新方法。给出了稳定性好的幅值控制电路。在多相SCO的设计中,幅值控制电路的复杂程度不随振荡器的相数增加而增加。实验结果与理论相符。
How to start oscillation and how to stabilize amplitude in SC oscillators are discussed. New methods for start-oscillation and amplitude-stabilization of SC oscillators are presented. The control circuitry with good stability for amplitude-stabilization is given. It is shown that the complexity of the amplitude-stabilization circuitry does not increase as the number of oscillator phases in the multiphase oscillator increases. The experimental results are in agreement with the presented theory.
