(a) An op-amp with an open-loop gain of Aod = 7 × 103 is to be used in an inverting op-amp circuit. Let R2 = 100 kΩ and R1 = 10kΩ. If the output voltage is υ0 = 7 V, determine the input voltage and the voltage at the inverting terminal of the op-amp. (b) If the output voltage is υO = −5 V and the voltage at the inverting terminal of the op-amp is 0.2 mV, what is the input voltage and the value of A0d ? .
