The circuit in Figure E.28 is a simple approximate model of an operational amplifier with the inverting input grounded
a) Define the excitation of the circuit as the current of a current source applied to the noninverting input and define the response as the voltage developed between the noninverting input and ground. Find the transfer function and graph its frequency response. This transfer function is the input impedance.
(b) Define the excitation of the circuit as the current of a current source applied to the output and define the response as the voltage developed between the output and ground with the noninverting input grounded. Find the transfer function and graph its frequency response. This transfer function is the output impedance.
(c) Define the excitation of the circuit as the voltage of a voltage source applied to the noninverting input and define the response as the voltage developed between the output and ground. Find the transfer function and graph its frequency response. This transfer function is the voltage gain.
