    How to measure gm accurately Reply
    How can I accurately measure the taransconductance (gm) of a transistor?

    What I have done is perform DC analysis, save DC operating points and then on ADEXL result pane under output pane, selecting direct plot from DC and get the transconductance (gm) as the ratio of terminal current to net voltage.

    Best Regard,

    Tuni

    Since gm is output as an operating point parameter of all transistor models that I'm aware of, couldn't you just use the OP function in the calculator to get this from your dc operating point analysis?
