(a) The transistor parameters are \(\beta=125\) and \(V_{A}=200 \mathrm{~V}\). A value of \(g_{m}=95 \mathrm{~mA} / \mathrm{V}\) is desired. Determine the required collector current and then find \(r_{\pi}\) and \(r_{o}\).

(b) A second transistor has small-signal parameters of \(g_{m}=120 \mathrm{~mA} / \mathrm{V}\) and \(r_{\pi}=1.2 \mathrm{k} \Omega\). What is the quiescent collector current and the transistor current gain?
