Hi, as I mentioned in one of my other posts, I was told that to reduce the time taken by the harmonic simulation it is good to use the model for the MOSFET.
I am not sure whether I can find this model in PDK. Where do we usually find and extract this model from PDK.

and about its parasitics Cgs,Cds and Cgd. I know how to get its operating point details from spectre. Can you be specific what exactly I need to know about the MOSFET model I use?
That is a dangerous thing to do.. When you are simplifying models, you are throwing away higher order effects. If you ignore higher order effects, or try to make an approximation out of it, then you will be losing crucial higher harmonic information. For example, your 2nd harmonic and fundamental often mix together to result in a component at your fundamental frequency which interferes with the operation of your circuit.
