3. The amplifier shown in Fig. 3 has \(R_{sig}= R_L=1 \text{ k}\Omega\), \(R_C=1 \text{ k}\Omega\), \(R_B=47 \text{ k}\Omega\), \(\beta=100\), \(C_\mu=0.8 \text{ pF}\), and the unity-gain frequency \(f_T=600 \text{ MHz}\).

(b) Neglecting \(r_o\), find the midband voltage gain (\(v_o/v_b\)) from base to collector (neglect the effect of \(R_B\)).
