Question:

For the circuit in Figure 6.3, \(\beta=120, V_{C C}=5 \mathrm{~V}, V_{A}=100 \mathrm{~V}\), and \(R_{B}=25 \mathrm{k} \Omega\).

(a) Determine \(V_{B B}\) and \(R_{C}\) such that \(r_{\pi}=5.4 \mathrm{k} \Omega\) and the \(Q-\) point is in the center of the load line.

(b) Find the resulting small-signal voltage gain \(A_{v}=v_{o} / v_{s}\).
