Digital compensation of nonidealities in time-interleaved ADCs
KTH, School of Electrical Engineering (EES), Signal Processing.
2014 (English)Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Mismatches between the analog to digital converters (ADCs) in time-interleaved sampling causes

spurious signals, limiting the performance of the architecture. This thesis introduces the most

commonly modeled mismatches, analyses their e ects and reviews and evaluates state-of-the

art compensation methods published in recent papers. A novel method for choosing calibration

signal for non-blind compensation is suggested, and how it can be used for current blind compensation

methods (relaxing input signal requirements). Application of some common compensation

methods is demonstrated with simulated data as well as data captured by a development board

with two time-interleaved ADCs sampling at a high rate.

Abstract [sv]

Skillnader mellan analog-till-digital-omvandlarna (AD-omvandlarna) vid tids-interleavad sampling

orsakar falska signaler, vilket kan bergransa arkitekturens prestanda. Den har masteruppsatsen

introducerar de skillnader som vanligtvis modelleras, analyserar dess e ekter och granskar

och utvarderar de framsta metoderna i nyligen publicerade artiklar. En ny metod for val av

kalibreringssignal till icke-blinda kompenseringsmetoder foreslas, och hur den kan anvandas for

blinda kompenseringsmetoder (vilket mildrar kraven pa insignalen). Nagra kompenseringsmetoder

tillampas pa simulerad data saval som data insamlad av ett utvecklingskort med tva

tids-interleavade AD-omvandlare med hog sampelfrekvens.
