摘要: 本文討論了開關(guān)電容振蕩器(SCO)的起振和幅值穩(wěn)定問題。提出了SCO的起振和幅值穩(wěn)定的新方法。給出了穩(wěn)定性好的幅值控制電路。在多相SCO的設(shè)計(jì)中,幅值控制電路的復(fù)雜程度不隨振蕩器的相數(shù)增加而增加。實(shí)驗(yàn)結(jié)果與理論相符。

Abstract: 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. -
