Question 2: Consider an op-amp connected in the inverting configuration to realize a closed-loop gain of -150 V/V utilizing resistors of 1 kΩ and 150 kΩ, with the following settings, where v is a low-frequency sine-wave signal of peak amplitude Vp. Let the op-amp be ideal, except its output voltage saturates at ±15 V and maximum current of ±20 mA. Hint: Consider using KCL at the output where io + i = iL. io: op-amp output current iL: load current i: feedback current
a) For RL = 2 kΩ, what is the maximum possible value of Vp while an undistorted output sinusoid is obtained?
b) Repeat question a) for RL = 100 Ω.
c) If it is desired to obtain an output sinusoid of 15 V peak amplitude, what minimum value of RL is allowed?
