Question: A feedback amplifier is needed which has an R _ ( it ) > = 1 M Omega and an R _ ( of

A feedback amplifier is needed which has an R_(it)>=1M\Omega and an R_(of)=100\Omega . The opamp
which has the equivalent circuit shown below is available for the application.
a. Briefly explain why series-shunt is the required feedback topology.
b. As necessary convert the equivalent circuit of the opamp to the proper equivalent
circuit for the type of feedback topology needed for this application.
c. What should be the value of the resistor R_(f)? Use the feedback circuit shown next to the
opamp equivalent circuit below.
d What is the value of the closed loop gain and the closed loop input resistance Rir?
A feedback amplifier is needed which has an R _ (
