Abstract

A high speed analog-to-digital converter employs a comparator having first and second units cross coupled in a positive feedback loop. The units are alternately connected to an input voltage and a reference voltage, after which positive feedback is introduced established, and a differential output established. The arrangement is fully symmetric, and balanced and rejects common-mode switching noise.
