Question:

Consider the ac equivalent circuit in Figure P6.73. The transistor parameters are $\beta_{1}=120, \beta_{2}=80, V_{A 1}=V_{A 2}=\infty$, and $I_{C Q 1}=I_{C Q 2}=1 \mathrm{~mA}$.

(a) Find the small-signal voltage gain $A_{v 1}=V_{o 1} / V_{i}$.

(b) Determine the smallsignal voltage gain $A_{v 2}=V_{o 2} / V_{o 1}$.

(c) Find the overall small-signal voltage gain $A_{v}=V_{o 2} / V_{i}$.
