Classification: CPC H  G | IPC G  H

Claim 0:
1. A circuit for a voltage comparator comprising:
a first transistor;
a second transistor for receiving a first input voltage at a second transistor gate terminal and a third transistor for receiving a second input voltage at a third transistor gate terminal, the second transistor and the third transistor connected to the first transistor at a first node;
a fourth transistor and a fifth transistor, the fourth transistor connected to the second transistor at a second node and the fifth transistor connected to the third transistor at a third node;
one or more capacitors connected between the third node and a fourth node, the fourth node comprising the second transistor gate terminal;
one or more capacitors connected between the second node and a fifth node, the fifth node comprising the third transistor gate terminal;
a first switch arranged to selectively sample the first input voltage to the fourth node;
a second switch arranged to selectively sample the second input voltage to the fifth node;
a third switch arranged to selectively apply a bias voltage to the first node;
a fourth switch arranged to selectively apply the bias voltage to the second node; and
a fifth switch arranged to selectively apply the bias voltage to the third node.
