Abstract
A multiple-reference-embedded comparator (MREC) circuit includes a tail current source circuit; an input transistor pair, coupled to the tail current source circuit, configured to receive differential input voltages and perform a first pre-amplification to generate first differential amplified voltages according to the differential input voltages; and a plurality of embedded reference (ER) branches, each coupled to the input transistor pair, each configured to perform a second pre-amplification to generate second differential amplified voltages according to the first differential amplified voltages, and to perform a discrete-time comparison to generate differential output voltages according to the second differential amplified voltages.
