+//Given Data

+f=32;//feedback in dB

+//from the Bodes plot we get that Avo = 2510

+Avo = 2510;//gain

+disp('The parameters are R , r (for Rdash), C (for Cdash)');

+//Desensivity D = B*Rmo = Avo*(R/(R+r))

+//20log10(D ) = f

+k = f - (20*log10(Avo));

+//Let (R+r)/R = l

+l = 1/(10^(k/20));

+//R/(R+r) = fp/fz

+//For 45degree phase margin and 32dB of low frequency feedback we find by trial and error method from the graph

+fz = 10;//in MHz

+fp = fz*l;

+//to determine c we can arbitrarily choose R
