Homework Help: Transfer function of NMOS schematic

  1. Oct 25, 2009 #1
    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.
