Hi. There.
I have made a ring oscillator that generates extremely low frequency (30kHz to 230kHz for input voltage from 1 to 4v). This is done by 50um CMOS tech with 5v application.
The phase noise for the VCO is attached. The distortion from about 10kHz is obviously white noise so that I can ignore. However, my question is how you do decide if this phase noise is ok or not.
Any good calculation method or comparison for this phase noise?
Thank you for your kind and clever answers in advance
