Abstract
A comparator circuit provided with a hysteresis characteristic comprises an amplifier comparing an input voltage with a reference voltage, a voltage-clamping circuit clamping the output voltage of the amplifier at a first stabilized voltage or at a second stabilized voltage in response to the comparison output of the amplifier, and a feedback circuit generating a first feedback voltage or a second feedback voltage as the reference voltage in response to the output voltage level of the amplifier, whereby the hysteresis voltage of the comparator circuit is substantially independent of the variation in a power supply voltage for actuating the comparator circuit.
