Smart and Flexible Digital-to-Analog Converters proposes new
concepts and implementations for flexibility and self-correction of
current-steering digital-to-analog converters (DACs) which allow
the attainment of a wide range of functional and performance
specifications, with a much reduced dependence on the fabrication
process. DAC linearity is analysed with respect to the accuracy of
the DAC unit elements. A classification is proposed of the many
different current-steering DAC correction methods. The
classification reveals methods that do not yet exist in the open
literature. Further, this book systematically analyses
self-calibration correction methods for the various DAC mismatch
errors. For instance, efficient calibration of DAC binary currents
is identified as an important missing method. This book goes on to
propose a new methodology for correcting mismatch errors of both
nominally identical unary as well as scaled binary DAC currents. A
new concept for DAC flexibility is presented. The associated
architecture is based on a modular design approach that uses
parallel sub-DAC units to realize flexible design, functionality
and performance. Two main concepts, self-calibration and
flexibility, are demonstrated in practice using three DAC testchips
in 250nm, 180nm and 40nm standard CMOS. Smart and Flexible
Digital-to-Analog Converters will be useful to both advanced
professionals and newcomers in the field. Advanced professionals
will find new methods that are fully elaborated from analysis at
conceptual level to measurement results at test-chip level. New
comers in the field will find structured knowledge of fully
referenced state-of-the art methods with many fully explained
novelties.<
