(2) suppose the open-loop amplifier (or simply the OpAmp) in the above feedback
amplifier has the following simulated magnitude and phase response. Some of the data
points are given below:
f3 =175kHz, Mag(f;)= 42DB, Phase(f;) =-180deg
f, =120kHz, Mag(f;)= 48DB, Phase(f,) =-150deg
fo =100kHz, Mag(f.)=51DB, Phase(f.)=-135deg
fs = 85kHz, Mag(f;)=534B, Phase(f;)=-115deg
f =77kHz, Mag(f.)=55dB, Phase(f,) =-105 deg
f3 = 45kHz, Mag(f,)=57&B, Phase(f;) =-75 deg
