Question 7 7 Figure 5 shows an amplifier consisting of an op-amp connected to a single-supply class AB output stage. The amplifier has an input signal, V, that drives a load resistor, R₁. 10 V R1 C1 5 k 10 V 22μ Vout C2 R3 1 kg D1 1,D2 -10 v RL 22μ 50 2 R4 1 ΚΩ Figure 5: An op-amp with a class AB output stage Suppose V, is a sinusoidal voltage with an amplitude of 0.5 V. On the same set of axes draw the waveforms for V, and the voltage, Ve, at the emitters of Q₁ and Q₂ for at least two periods. Indicate the maximum and minimum values of both waveforms. Assume the op-amp is ideal and Vce(sat) is negligible for Q₁ and Q2. What is the maximum amplitude for V that results in an undistorted output? Vs R2 1 k Ne H Q1 C3 HH 5000μ Ve Q2
