At lower frequencies, the phase shift is smaller, so no problems arise. At frequencies between f1 and f2, the magnitude of the open-loop gain falls, and the phase remains at −90°, so the amplifier is still stable. At f2 and above, the phase of the open-loop gain approaches −180°, making the loop gain positive.
