    I have this amplifier, a small signal transistor driving class AB

    from the output of class AB stage, its connected back to base of the
    small signal transistor .

    how do I calculate gain of this amplifier.

    best wishes

    Gain (G) depends on the amount of negative feedback (B).

    G ~ 1/B
  3. If the first base also has an input resistor, then the gain is
    probably -(feedback resistance)/(input resistance), approximately.
