Apparently there are so many kinds of known oscillator structure that does not expect LC-tank. I'd like to ask you what fully on-chip oscillator topology you think best around a few tens of MHz in terms of jitter/power/area/psrr. RC oscillator? or n-stage ring oscillator? and Why?
Hi there,
Apparently there are so many kinds of known oscillator structure that does not expect LC-tank. I'd like to ask you what fully on-chip oscillator topology you think best around a few tens of MHz in terms of jitter/power/area/psrr. RC oscillator? or n-stage ring oscillator? and Why?
Thanks for kind discussion in advance
Some important specifications are missing:
*What kind of signal do you want ?
*Specific quality requirements?
*Any external frequency tuning/adjustment required?
