    1. The problem statement, all variables and given/known data[/b]
    Hi, just wondering if anyone could help me with this problem?
    Find vout / vin in terms of Rf R1 R2.
    And which model should I use if I want to get the output voltage Vout 2V DC 2V p-p if the input voltage is Vin = 50mV p-p?

    2. Relevant equations
    Ic + Ib = Ie
    Ic = Ib (B) in active region



    3. The attempt at a solution
    V1 = IeR1+ IbRf + Vbe
    Vc = V1 - Ic(R1+R2) ...
