Abstract
A comparator circuit has a sense amplifier with a differential pair, a voltage excursion limiter, and a switch. The differential pair receives two analog input signals. Its differential outputs operate at a common mode voltage approximately half the supply voltage. The voltage limiter is coupled with one of the differential pair outputs. A capacitor may store comparison results. The switch energizes the differential pair and the voltage excursion limiter during a first phase of a clock, and de-energizes them during a second phase of the clock. During this phase, the comparator may provide the stored comparison result to an amplifier with positive feedback.
