What is the unity gain frequency?

The unity-gain bandwidth of an amplifier is simply the frequency of an input signal at which the open-loop gain is equal to 1. Note that the open-loop gain is the measured maximum gain of the amplifier when no components are present in the feedback loop. This frequency is referred to as the unity-gain bandwidth.
