##### Reference no: EM13868195

Problem: A op-amp has unity-gain bandwidth of 105Hz. Its gain at very low frequency is 80 dB. You are using the op-amp in the inverting configuration with a signal that is at about 10 kHz. The op amp has a 10kΩ resistor in the feedback position and a 3 kΩ resistor in the input position. (It is also important to note that the open-loop gain of the op-amp has single pole).

a. Find the open-loop gain of the op-amp at 10kHz in unit of V/V

b. Find the corner frequency of the op-amps open loop gain

c. Find the straight-through (Forward path) gain of this configuration at 10 Khz

d. Find the loop gain of this configuration at 10 kHz.

e. Find the overall gain of this configuration at 10 kHz.
