Could anyone please help me with this question?
I need to simulate my ring oscillator's output in frequency domain, showing a continuous spectrum waveform as it can be seen from spectrum analyzer in the measurement (PSS->THD is not what I want).Then I can derive Q directly from it.
If there is a detailed guide, that would be very helpful.
Thanks a lot.
It's still not clear to me what you're trying to do, so I would suggest contacting customer support so you can share the data with us and we can help you out with full visibility rather than having to guess.
