Abstract
A comparator having programmable hysteresis is provided. The signal supplied to an inverting input of the comparator (18) is determined by the logic state of the output of comparator and is a programmable factor of one of two predetermined signals (V.sub.REF1 or V.sub.REF2). The programmable factor is determined by the logic states of a plurality of control signals and can be adjusted by varying the logic states of the plurality of control signals.
