An analysis of interconnection network effects of dynamic element matching digital-to-analog converters
type: CreativeWork
description: Digital-to-Analog Converters (DACs) convert digital signals into analog signals and thereby provide the link from digital systems to the analog world. Many DAC architectures use matched components to convert signals. However, practical DACs contain mismatched circuit components that cause nonlinear errors in the DAC's analog output signal. Dynamic Element Matching (DEM) is a method that can eliminate or reduce the effects of mismatch errors. In this thesis, DEM algorithms applied to a specific DEM DAC architecture that use several interconnection networks, including the Barrel Shifting network, the Generalized-Cube network, the Omega network and the Indirect Binary n-cube network, are mathematically analyzed. The hardware complexity of some networks is discussed and a new interconnection network is developed and is shown to be hardware efficient when applied to the specific DEM DAC architecture.
