For the circuit in Figure 6.14, \(\beta=100, V_{A}=\infty, V_{C C}=10 \mathrm{~V}\), and \(R_{B}=50 \mathrm{k} \Omega\).

(a) Determine \(V_{B B}\) and \(R_{C}\) such that \(I_{C Q}=0.5 \mathrm{~mA}\) and the \(Q\)-point is in the center of the load line.

(b) Find the small-signal parameters \(g_{m}, r_{\pi}\), and \(r_{o}\).

(c) Determine the small-signal voltage gain \(A_{v}=v_{o} / v_{s}\).
