At least to up to this point the Vf versus Cf arguements have been independent of model accuracies.
Eventually, hopefully we get to were we need to refine this to determine the proper topology within the constraints.


Thanks

Of course it s not +-1%.
I mean by a 2 ratio -50% to +100% error in THD evaluation.

Fortunately gain and phase response computation are way
more accurate for obvious reasons.

Sorry for the OT, I'm off my soapbox now.
I had no idea about foundries models accuracy , to be honnest
i thought that it was better than the numbers you re quoting
given the relative complexity of V/ULSI circuits.
