Abstract

In this paper, we investigate data converters that exploit the possibilities of advanced digital signal processing. After discussing the necessity and prospects of digital signal processing for data converters to comply with next generation system specifications, we demonstrate three examples of digitally enhanced data converters: time-interleaved analog-to-digital converters, all-digital phase-locked loops, and predistorted power amplifiers. To this end, we extend the term of a data converter to a cooperating system that includes digital and analog pre/postprocessing units to fullfil the required specification.
