Springer Smart and Flexible Digital-to-Analog Converters (Analog Circuits and Signal Processing)

Product Description With proposals for new concepts in the flexibility and self-correction of DACs that should enable a range of functional and performance specifications, this book’s detailed coverage is ideal for seasoned professionals and newcomers to the field alike. Review From the reviews:“This is a very useful book on the state of the art in the field of digital-to-analog conversion (DAC) methods whose main aim is to advance the existing knowledge on efficient and robust high-performance current-steering DACs, and to investigate the concept of DAC flexibility. The authors focus on the accuracy and they stress DAC correction methods to achieve it and to provide high efficiency. … The list of references contains 94 items, most of them published recently.” (Vladimir Čadež, Zentralblatt MATH, Vol. 1217, 2011) From the Back Cover 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.
