Question:

Consider the circuit shown in Figure 7.15 with parameters $R_{S}=0.5 \mathrm{k} \Omega$, $r_{\pi}=5.2 \mathrm{k} \Omega, g_{m}=29 \mathrm{~mA} / \mathrm{V}$, and $R_{L}=6 \mathrm{k} \Omega$. The corner frequencies are $f_{L}=30 \mathrm{~Hz}$ and $f_{H}=480 \mathrm{kHz}$.

(a) Calculate the midband voltage gain.

(b) What are the open-circuit and short-circuit time constants?

(c) Deter$\operatorname{mine} C_{C}$ and $C_{L}$.
