For the output stage of Fig. 5.20a, assume that V CC = 15 V, β F (pnp)
Question:
(a) Calculate the maximum positive and negative limits of Vo for RL = 10 kΩ, RL = 1 kΩ, and RL = 200 Ω.
(b) Calculate the maximum average power that can be delivered to RL = 1 kΩ before clipping occurs, and the corresponding circuit efficiency (for the output devices only). Also calculate the peak instantaneous power dissipation in each output device. Assume sinusoidal signals.
