2.122 Consider an op amp connected in the inverting configuration to realize a closed-loop gain of −100 V/V utilizing resistors of 1 k and 100 k. A load resistance RL is connected from the output to ground, and a low-frequency sine-wave signal of peak amplitude Vp is applied to the input. Let the op amp be ideal except that its output voltage saturates at±10 V and its output current is limited to therange±20 mA. (a) For RL = 1 k, what is the maximum possible value of Vp while an undistorted output sinusoid is obtained? (b) Repeat (a) for RL = 200 . (c) If it is desired to obtain an output sinusoid of 10-V peak amplitude, what minimum value of RL is allowed?
