Plot the DC transfer characteristic $($Vo vs$.$ Vi$)$ and estimate the Gain $($make sure you use a step size less

than $1$ mV $).$ Compare this gain with your hand calculation and $1$ d $.$ Comment

Frequency compensate the OPAMP in order to get a phase margin of $45$ degrees or more for unity

feedback $($configured as a unity gain amplifier$).$ The best compensation scheme is the one that yields the

highest bandwidth while maintaining at least $45$ degrees phase margin.

a$.$ Report your best result by showing a bode plot of the magnitude and phase of the loop gain.

b$.$ Draw the schematic of the compensated OPAMP with all the component values. This is the

optimized and final design.

c$.$ Report the new value for the dominant pole and label it on your plot. What is the bandwidth of

the compensated amplifier?

d$.$ Compare the bandwidth of the uncompensated amplifier vs the compensated amplifier, explain.

$($compare the stability of the compensated vs$.$ uncompensated amplifiers and their bandwidths$)$

With the optimized OPAMP you found in part $3$:

a$.$ Design a non$-$inverting amplifier with a gain of $20$ dB $.$ Report the values of the feedback resistors

used

b$.$ Find by using hand analysis and simulation, the input impedance of this amplifier

c$.$ Run an AC simulation to $1$ GHz
