Question:

Figure P6.62 shows an ac equivalent circuit of a common-base amplifier. The parameters of the transistor are $\beta=120, V_{B E}(\mathrm{on})=0.7 \mathrm{~V}$, and $V_{A}=\infty$.

(a) Determine the quiescent values $I_{C Q}$ and $V_{C E Q}$.

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

(c) Find the small-signal current gain $A_{i}=I_{o} / I_{i}$.
