Abstract
Comparators using hysteresis were widely used in IC design. The paper first introduces the design of the conventional comparator using hysteresis and its disadvantage for the low-threshold compare. Then a novel low-threshold comparator using hysteresis is developed. The threshold and width of the new comparator can be reduced to the mV range, the resolution and the dynamic characteristics are also good. Finally, a typical application of the new comparator using hysteresis is given for the AC-DC control circuit. Its threshold is 50mV and width is 20mV
