Abstract
A comparator includes a pair of back-to-back negative-AND (NAND) gates and a delay circuit coupled to the pair of back-to-back NAND gates. The delay circuit is configured to modulate a triggering clock signal by an input voltage to generate a delayed clock signal with a delay that is based on the input voltage. Each of the pair of back-to-back NAND gates is configured to receive the delayed clock signal and generate a comparator output signal based on the delayed clock signal.
