ABSTRACT:
A chopper comparator has inverters in input and output stages including NMOS transistors to control connection and disconnection of an inverter circuit of each inverter. During a non-operation period of the chopper comparator, parts of the inverters are disconnected form the ground based on a signal supplied to gates of the NMOS transistors.
