ABSTRACT:
A comparator includes a differential amplifier, and a hysteresis circuit. The differential amplifier amplifies a difference signal corresponding to a difference between input signals. The hysteresis circuit sets up a first transition threshold voltage and a second transition threshold voltage where the second transition threshold is different from the first transition threshold voltage. The hysteresis circuit generates a second signal that makes transition at the first transition threshold voltage when the difference signal changes in a first direction, and makes transition at the second transition threshold voltage when the difference signal changes in a second.
