Q4. The open-loop gain of the multistage CE amplifier has break frequencies at f_{p 1}=805 k H z, f_{p 2}=9.6 M H z f_{p 3}=13 M H z_{1} \text {

and } f_{p 4}=61 M H z = midfrequency gain is A mid = 9594 determine the value of compensating capacitance cx that will give a closed loop phase margin 45 with a resistive feedback of upto b=1
