An inverting operation amplifier with a negative feedback circuit has Rf = 1 M Ohm and Ri = 10 k Ohm. Assume that at this point when Av*β = 1, phase shift due to the amplifier is 120 degrees. A 0.001 micro farad capacitor is added in parallel with Rf in the feedback circuit. What is the new phase shift at the frequency where Av*β = 1?
