the open loop ac response of an fully differential opamp is shown in the picture, the phase margin is 127deg as shown, please give some comment and is there any potentional problem based on the ac response you observe?
 

Phase margin is 180-127 = 53 deg. Confuse nonlineriaty of ac on 100-120 Meg. It may reduce to poor slew rate and large harmonic distortions
