behavioural amplifier models - P2D vs. VCA

Question asked by LI04124 on Feb 26, 2008

on system level I often use analog cosimulation with P2D-amplifier models or VCA-models.
With P2D I have all nonlinear effects (AM-AM, AM-PM) vs. frequency included but always a ideal power supply.
With VCA I can simulate non-ideal time-varying power supplies but cannot include frequency responses as it is a single frequency model, correct?

Is there a way to somehow combine these two types of models into one, so that I get a model that includes AM-AM/PM behaviour vs frequency, power and supply voltage?

Any suggestions are highly appreciated!

Best regards,
