Question
Consider a three-pole feedback amplifier with a loop gain function given by Bx1000 T(f)=; 1+j- f 1+ j• 5×10°, f 1+ j• 10° 10' a) Determine the value of ß that yields a phase margin of 45 degrees. What is the value of closed loop low frequency gain for this case? b) If ß is changed to 0.14, determine the new closed loop low frequency gain and the approximate phase margin.
