A two-transistor series voltage feedback amplifier is shown in Figure P2.24(a). This AC equivalent circuit neglects the bias resistors and the shunt capacitors. A block diagram representing the circuit is shown in Figure P2.24(b).This block diagram neglects the effect of hie, which is usually an accurate approximation, and assumes that R2 + RL >> R1.
(a) Determine the voltage gain v0/vin.
(b) Determine the current gain iin/lb1.
(c) Determine the input impedance vin/ib1.
