Abstract
A differential comparator is disclosed including first and second input amplifier circuits. The input amplifier circuits have respective signal input terminals for receiving respective first and second complementary input signals and respective output terminals. The first and second input amplifier circuits cooperate to produce a difference signal. Reference signal circuitry is coupled to the input amplifier circuits and is operative to produce a predetermined reference signal for comparison to the difference signal. The input amplifier circuits and the reference signal circuitry cooperate to define a single stage.
