Abstract

See full text

A comparator circuit includes a zeroth capacitor having a first terminal fed with an input voltage, a zeroth inverter having an input terminal connected to a second terminal of the zeroth capacitor at a zeroth node, a first capacitor having a first terminal connected to the output terminal of the zeroth inverter at a first node, a first inverter having an input terminal connected to a second terminal of the first capacitor at a second node, a second inverter having an input terminal connected to the output terminal of the first inverter at a third node, a zeroth switch switching conduction between the zeroth and first nodes, a first switch switching conduction between the second and third nodes, a second switch switching conduction between the first and third nodes, and a third switch switching conduction between the third node and the output terminal of the second inverter.
