Abstract
A comparator is disclosed, for comparing a first input voltage with a second input voltage and generating a corresponding output voltage. The comparator includes a follower stage coupled to a first supply rail and a second supply rail, a follower stage input terminal for the second input voltage, and a follower stage output terminal. The comparator also includes an inverter stage comprising a first inverter stage supply terminal coupled to the first supply rail, a second inverter stage supply terminal coupled to the follower stage output terminal, an inverter stage input terminal for the first input voltage, and an inverter stage output terminal for providing an inverter stage output voltage having a first range. A signal conditioning means is coupled to the inverter stage output terminal and generates a comparator output voltage at a comparator output terminal having a second range larger than the first range.
