Hi all, I want to design VCO in MHz. ring oscillator is one choice. But I don't understand relaxation oscillator.
1. Does it have better phase noise compared to Ring osc.?
2. What's the drawback of relaxation oscillator? I can only find bad temperature frequency stability.
3. What's its advantage?
3. What's the control signal for relaxation oscillator? Someone said it only support current control but not voltage control.
Is there some book or paper which introduce relaxation oscillator in detail?
Thanks!
