Dear All,
I'm using ADS Dynamic Link to simulate an LC oscillator schematic from cadence(using ibm130nm PDK). With the ADS HB simulation, all the simulation results such as oscillation freq are obtained correctly except for the phase noise(pnmx). When I list the pnmx in the result browser window, the value shows "NaN". Can anyone tell me what is the problem and how to fix it?
BTW, I have also run an s-parameter simulation and see the noise figure of some similar two-port network consisting of mosfet and passive elements, the noise figure shows correct results. So it may not be the problem that Dynamic link did not import mosfet noise model into ADS correctly.
Thank you very much.
