Abstract

A hysteresis system with constant threshold voltage, regardless of an increase or decrease of an output signal by detecting the increase/decrease state of the input signal, and includes a second voltage signal generator for generating a second voltage signal which is gradually increased when a first voltage signal inputted is high and is gradually reduced when the first voltage signal inputted is low, a voltage comparator for comparing the reference threshold voltage signal with the second voltage signal generated from the second voltage signal generator and producing a corresponding value; a threshold voltage initialization circuit for comparing reference voltage with the first voltage signal inputted and producing a threshold voltage initialization signal in accordance with a corresponding value; and a threshold voltage generator to which an output signal produced from the voltage comparator and the threshold voltage initialization signal produced from the threshold voltage initialization circuit are fed back, for producing a threshold voltage signal corresponding to a feedback value.
