    Does common-mode voltage depend on the AC amplitude of the input at the gate?

    hi,

    i have a very simple question. does the output common-mode voltage of a simple differential amplifier depend on the input AC amplitude at the gate? why or why not?
    thanks

    common mode output range is range which your differential amplifier is still working in forward acive region.

    common-mode voltage

    common mode output voltage does not depond on the input common mode voltage.

    Voc = Ac Vc, so it depends on the amplitude of Vc and the common mode gain
