Question

Find the closed-loop transconductance, input resistance, and output resistance for the series-series feedback amplifier as shown if the op amp has an open-loop gain of 80 dB, an input resistance of 25kΩ , and an output resistance of 1kΩ. Assume the amplifier is driven by a signal voltage with a 10-kΩ source resistance, and the feedback network is implemented with R2=91kΩ and R1=10kΩ.
