how about the accuracy of a cmos spice model in RF freq

The model is a standard bsim3 model for digital circuit design.
How about its accuracy in 10 or 20GHz or above during the analog design?

It depends on how much and how accuracy of parasitics information in the model.

Hi

The typical trend in this range is S-parameters.

Try to map your problem into s-parameters.
OR
use spice to s-parameters tools.



tnx
