Abstract textA hysteresis circuit applied to a comparator and an amplifier circuit thereof are provided. A hysteresis circuit is disposed on a positive feedback path of the comparator, such that the comparator resists noise interferences, and the hysteresis circuit has a feature of not affecting the feedback voltage signal, thereby making the hysteresis range of the comparator be more precise. |
