Hello everyone,
Sorry if I missed the topic and the question is already answered.
I want to simulate the phase noise contribution of an MMD used in a frequency synthesizer. For the purpose of simulation, the division is integer ( divide by N ). I use PSS and add Beat frequency to be Fvco/N ( where Fvco is the vco output frequency ).
Also i add harmonics to be 5*N ( that would equal to 5 harmonics of Fvco).
Then in Pnoise simulation , I use 10 maximum sidebands and add the voltage nodes I am interested in ( output nodes of MMD ). Im measuring relative harmonic 1 also.
Is this the correct way to simulate a divider or am I missing something?
Thank you in advance
PS: The simulator i use is SpectreRF in Cadence Virtuoso
