High-speed Hysteresis-based Comparator

Comparator with hysteresis is useful in a noise environment. Comparator with hysteresis has higher power dissipation due to extra circuitry.

Output of a Comparator without Hysteresis: showing Multiple Transitions near Threshold:

Output of a Comparator with Hysteresis: showing Single Transitions near Threshold:

Simulated Current during Comparator Operation:
