1. The problem statement, all variables and given/known data Problem number 6a in the picture. 2. Relevant equations Transistor: Ic = βIb Ic = αIe Ic = Is*e^(Vbe/nVt) OP-Amp: Vo = Acl*Vi Acl = 1 + (Rf/Ri) 3. The attempt at a solution I tried to solve but just couldn't understand the behavior the transistor.
