Abstract
This document describes a simple modification to the traditional pipelined analog-to-digital converter (ADC) architecture that reduces the signal swing of the inter-stage amplifier by a factor of two. This is a significant advantage when low power supply voltages limit the output range of operational amplifies. The modification requires no additional hardware and produces no additional power consumption.
