Abstract：Hysteresis comparatorisacomparator circuit with hysteresis characteristics，which is widelyused inelectronic circuits.Intheteachingprocessofhysteresiscomparator，terearesomeproblem，suchasstudents'understandingof theconcept of“hysteresis”is notdeep enough，andthey lack the ability to aply the hysteresis comparatorin practice.Therefore，this paperfirst makesaconcise theoretical analysisof thehysteresiscomparator，andthen takes theapplicationofthe hysteresis comparator inthetemperaturecontrolsystem asanexample todesignatemperature hysteresis adjustment circuit.This paper introduces thedesignrequirementsandschemes，focusesonhowtodesignthecircuit，gives theProteus simulationcircuit，and completestheProteus simulationverification，soas tocombinethetheoretical knowledge withthepracticalsimulation，and discusses the practicalaplicationofthehysteresiscomparatorwhichcanprovidereferencefor theteachingandlearing of the hysteresis comparator.
