For the common-base circuit shown in Figure P6.67, let \(V_{C C}=5 \mathrm{~V}\), \(R_{L}=12 \mathrm{k} \Omega\), and \(R_{E}=500 \Omega\). The transistor parameters are \(\beta=100\) and \(V_{A}=\infty\).

(a) Design the circuit such that the minimum small-signal voltage gain is \(A_{v}=v_{o} / v_{s}=25\).

(b) What are the \(Q\)-point values?

(c) Determine the small-signal voltage gain if \(R_{2}\) is bypassed by a large capacitor.
