Disclosed is a low hysteresis center offset comparator, comprising a first switch device, a differential amplifier, a second switch device, a general comparator, a first inverter and a second inverter. By means of the components, a hysteresis window with the low hysteresis center offset may be formed with respect to the inventive comparator with a width of a half-portion thereof formed equal to that of the other half-portion thereof corresponding to an offset voltage inherent in the differential amplifier.
