摘要:
It is shown that the performance of anRC-active oscillator proposed by Reddy is sensitive to loop-gain errors and that designs based on minimising excess phase shifts are less than optimum. A modified design which reduces the frequency sensitivity to uniform gain-bandwidth product variations to near zero is presented, together with analytical support and experimental details.
