For a Non-compensated/Decompensated Operational Amplifier withthe following poles:

Suppose de Open-Loop Gain for f1 is:

The Output Resistor of the Op Amp is 100 Ohms

Using the method of LAG compesator method (simple lag,multiplying by a simple pole) to guarantee that the Phase Margin isequal to 45 degrees. The configuration of the LAG compesator is shown in the image below:

Answer the folliwing questions for this system:

a) What frequency in MHz of the pole that is added to the systemwhen is compensated?

b) What should be the value of the capacitor in uF added tothe system?

c) What would be the bandwidth in MHz for the circuit?
