Question:

A simplified class-AB output stage with BJTs is shown in Figure 8.24. The circuit parameters are \(V_{C C}=5 \mathrm{~V}\) and \(R_{L}=1 \mathrm{k} \Omega\). For each transistor, \(I_{S}=2 \times 10^{-15} \mathrm{~A}\).

(a) Determine the value of \(V_{B B}\) that produces \(i_{C n}=i_{C p}=1 \mathrm{~mA}\) when \(v_{I}=0\). What is the power dissipated in each transistor?

(b) For \(v_{O}=-3.5 \mathrm{~V}\), determine \(i_{L}, i_{C n}, i_{C p}\), and \(v_{I}\). What is the power dissipated in \(Q_{n}, Q_{p}\), and \(R_{L}\) ?
