Cadence simulate ring oscillator's output in frequency domain (continuous wave)

chiphead

 Hi,

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.

    Regards,

    Andrew.
