Design of high order mismatch and ISI shaping dynamic element matching decoders for delta sigma data converters

O'Brien, Vincent (University of Limerick, 2017)

This thesis presents the analysis and design of dynamic element matching (DEM) decoders targeted at both discrete and continuous time oversampling delta sigma data converters. Discrete time delta sigma data converters ...
High order mismatch shaping for low oversampling rates

O'Brien, Vincent; Mullane, Brendan (IEEE Computer Society, 2020)

Delta Sigma data converters employing high order dynamic element matching (DEM) allow for accurate signal conversion in the presence of DAC mismatch. However, at low oversampling rates, current high order DEM decoders ...
A wideband 6th order programmable bandpass DEM implementation for a Nyquist DAC

Mehta, Shantanu; Mullane, Brendan; O'Brien, Vincent; Pelliconi, Roberto; Erdmann, Christophe; Farley, Brendan (IEEE Computer Society, 2020)

This paper presents a 6th order programmable bandpass dynamic-element-matching (DEM) that shapes the static mismatch error of a Nyquist DAC for any choice of center-frequency. The mismatch error can be shaped over a ...
