1. The problem statement, all variables and given/known data
Attachment titled Clapp Schematic is what I am finding the transfer function of. Results are obtained with small signal, low frequency, equivalent circuit for a common-source NMOS.
2. Relevant equations
I have derived two different formulas, looking at Vo in 2 different ways.
3. The attempt at a solution
My 2 results are in the last 2 images attached, where I derive 2 different expressions for Vo/Vi.
Having the transfer function, we set Im[H(s)] = 0 to find resonant frequency, but as can be seen from my derivation, it is not possible.
