Abstract
A regenerative comparator provides the capability of operating faster than a traditional regenerative comparator and the hysteresis points can be individually set and fine tuned. The regenerative comparator includes a current mirror having an input transistor connected to first and second output transistors, a first and second reference current sources which are set at a first and second predetermined level, respectively. An outputs of the first and second output transistors are provided to the latch through an inverter. The output of the latch transitions from a first logical output state to a second logical output state when an input current increases from a magnitude less than the first predetermined level to a magnitude greater than the first predetermined level.
