Abstract

A precise over-voltage comparator exhibits zero-waiting-current characteristics during normal working conditions. An NMOS transistor is used in conjunction with other circuit elements to regulate the over-voltage comparator. For normal power supply voltages, the comparator stays in standby status and does not consume quiescent current.
