Hi all~
I'm trying to simulate the phase noise of my VCO and I used EM simulator to extract port to port s-parameters (all ports including IND and MOS,,...) and applied the results to cadence schematics through nport in analogLib.
PSS/Pnoise results of phase noise in cadence was so bad and it shows difference of more than 10dBc/Hz compared to "only inductor is Em simulated version". Is this natural case?
Which one do I have to believe. wholly em simulated case? or case of only the inductor is simulated.
Or am I simulating the phase noise of VCO in incorrect method?
Thanks!
