BJT Differential Amplifier

  1. Nov 16, 2009 #1
    In a BJT Differential amplifier, how to find the maximum and minimum values of the common-mode input voltage? Beta and the resistors are given.

    Doesn't that depend on the input circuit? I mean, that is an input to the amplifier. All the amplifier itself can do is to partially reject the common mode input voltage that is given to it.
