    Hi all,
    I am trying to find Ft in cadence for just a single PMOS
    transistor and I am not able to do it so far. I am using a single
    PMOS, a DC voltage source Vdc , one in drain ans one in gate for
    biasing and also an DC current source acm parameter as 1 A . this
    current source is in series with my DC voltage source for gate.

    I ran an ac analysis and tried to find the current ratio
    between drain and gate through calculator. then i tried to plot it
    against frequency. I am sure that the graph is wrong.

    so could anyone tell me as how to plot this one in a right
    way.many thanks in advance.
