    Calculate Miller Capacitance from Model Parameters in Cadence

    Dear all,

    How to calculate miller capacitance from the model parameters of a transistor that's biased up?

    Another related question is that when I want to use simple equation to find a particular parameter, say use Cgs as part of ft expression, how to find this capacitance? Since there are Cgs, Csg (for Cgd, there is also Cdg)?

    Thank you.

    Re: Calculate Miller Capacitance from Model Parameters in Cadence

    Those parameters are inputs, not results, and Cxx swing all
    over the place with bias. If you want to calculate them, dig
    up the model equations (for whichever model you are using,
    of the many possible) and have yourself a time. You would
    be better off with the OP results if you don't want to waste
    an afternoon.
