Abstract
A pipeline analog-to-digital conversion system (10) includes a plurality of cascaded subconverter stages (12) and a digital correction unit (18). Each subconverter stage (12) includes an n-bit analog-to-digital converter (36), an n-bit digital-to-analog converter (38), and an arithmetic unit (42). Arithmetic unit (42) simultaneously samples a second input analog signal (34) and produces an output analog signal (44) representative of the difference between a first input analog signal (32) and a corresponding intermediate analog signal (40).
