| Zusammenfassung: | A comparator with hysteresis which has a bias current circuit, a differential input stage, and an output stage is disclosed. The differential input stage uses a parallel transistor and an enabling transistor connected in parallel to one of the differential pair transistors to create hysteresis. The parallel transistor and enabling transistor are used to generated an effective offset voltage which must be overcome for the comparator to switch states. |
