Abstract

Systems and methods are provided for a pipelined analog-to-digital converter (ADC) circuit. The pipelined ADC circuit comprises a plurality of stages. Each stage comprises a differential input configured to receive a differential signal, a multiplying digital-to-analog converter (MDAC) electrically coupled to the input configured to stack voltages of a set of capacitors; a comparator electrically disposed after the MDAC to compare the differential voltages; and a source follower buffer electrically coupled to the first signal line and the second signal line and electrically disposed after the comparator, wherein the MDAC is configured to amplify an output voltage using passive multiplication; and an alignment circuit communicatively connected to a digital bit output of each stage of the plurality of stages, wherein the alignment circuit is configured to delay a digital bit output of each stage for one or more clock cycles and output a digitized representation of a sampled differential signal.
