Classification: CPC H | IPC H

Claim 0:
1. A comparator circuit comprising:
a zeroth capacitor configured to have a first terminal to which an input voltage is applied;
a zeroth inverter configured to have an input terminal connected to a second terminal of the zeroth capacitor at a zeroth node;
a first capacitor configured to have a first terminal connected to an output terminal of the zeroth inverter at a first node;
a first inverter configured to have an input terminal connected to a second terminal of the first capacitor at a second node;
a second inverter configured to have an input terminal connected to an output terminal of the first inverter at a third node;
a zeroth switch configured to switch between conducting and cut-off states a path between the zeroth and first nodes;
a first switch configured to switch between conducting and cut-off states the path between the second and third nodes;
a second switch configured to switch between conducting and cut-off states the path between the first and third nodes; and
a third switch configured to switch between conducting and cut-off states the path between the third node and an output terminal of the second inverter.
