Consider the power-op-amp output stage shown in Fig.
Chapter 11, Problem 11.51(choose chapter or problem)
Consider the power-op-amp output stage shown in Fig. 11.39. Using a 15-V supply, provide a design that provides an output of 11 V or more, with currents up to 20mA provided primarily by Q3 and Q4 with a 10% contribution by Q5 and Q6, and peak output currents of 1 A at full output (+11 V). As the basis of an initial design, use = 50 and for all devices at all currents. Also use R5 = R6 = 0.
