An inverting amplifier circuit has a voltage gain of -25 . The op-amp used in the circuit has a low-frequency voltage gain of \(5 \times 10^{4}\) and a unity-gain bandwidth of \(1 \mathrm{MHz}\). Determine the dominant pole frequency of the opamp and the small-signal bandwidth, \(f_{3-\mathrm{dB}}\), of the inverting amplifier. What is the magnitude of the closed-loop voltage gain at \(0.5 f_{3-\mathrm{dB}}\) and at \(2 f_{3-\mathrm{dB}}\) ?
