Abstract

A mixed-signal implementation of an iterative bound-based nonlinear data acquisition decoding algorithm for first-order delta-sigma (DeltaSigma) analog-to-digital converters (ADCs) is discussed. The design is partitioned into analog and digital sections which optimize the design objectives of very small area while maintaining low power and high speed. The circuit has been realized using 0.7mm² in 0.5mum CMOS technology and is estimated to occupy 0.44mm² without test circuits
