Abstract

See full text

A system and method for detecting signal levels in a multi-level signaling receiver. In one embodiment, a plurality of comparators, each including a differential pair, such as a differential pair of field-effect transistors (FETs) are assembled in a stacked configuration so that in some states current flows through FETs of the plurality of differential pairs in series, resulting in a reduction in power consumption.
