Abstract :
In this paper we present a novel method for combining thermometer coding and dynamic element matching (DEM) in a digital-to-analog converter (DAC). The proposed method combines DEM with a minimization of glitch power. The glitch power may in a DEM solution make a significant contribution to the total noise power. The switch based solution provides a structural solution where it is possible to implement parts of the method, which reduce the area required for implementation
