Have you checked the process characterization report-or the name that TSMC gives to it-?, in this document should be data about the error between the model and the measurements and up to which frequency it was measured, in the 0.18um process that I'm using(not TSMC) 10GHz was included in the model according to this report.
Hope it helps,
Thanks for the reply.
However, this lead to another question. Designing a VCO in 10G may have a resonant tank's Q dominated by the varactor. This varactor might not be very well modeled, so that the tank impedance at resonance is hard to model.
How can I make sure it will start-up and how much current should I feed...? Tough.
