Mixed-signal implementation of a nonlinear decoder for delta-sigma encoded stream

Abstract

A mixed-signal implementation of an iterative estimate, X, of the input x[n] based on the known values of bound-based nonlinear data acquisition decoding algorithm y[n]. In [7], a detailed mathematical development of the for first-order delta-sigma (As) analog-to-digital converters proposed iterative bound-based decoding algorithm is (ADCs) is discussed. The design is partitioned into analog and presented. X ts shown to be bounded as in (1), where S[n] is digital sections which optimize the design objectives of very defined in (2). A more accurate estimation of can be small area while maintaining low power and high speed. The achieved by using the bound in (1) iteratively with n=1.L. circuit has been realized using 0.7mm2 In 0.5,um CMOS 2i .
