The parameters of the circuit shown in Figure P7.52 are changed to \(V^{+}=5 \mathrm{~V}, R_{S}=0, R_{1}=33 \mathrm{k} \Omega, R_{2}=22 \mathrm{k} \Omega, R_{C}=5 \mathrm{k} \Omega\), and \(R_{E}=4 \mathrm{k} \Omega\). The transistor parameters are \(\beta_{o}=150, C_{\mu}=0.45 \mathrm{pF}\), and \(f_{T}=800 \mathrm{MHz}\).

(a) Determine \(I_{C Q}\) and \(V_{C E Q}\).

(b) Determine \(C_{\pi}, f_{\beta}\), and the Miller capacitance \(C_{M}\).

(c) Find the upper \(3 \mathrm{~dB}\) frequency.
