Abstract
This paper presents a novel dynamic element matching (DEM) method called Thermo Data Weighted Average (TDWA) for Nyquist-rate current - steering digital to analog converter (DAC). When the input code changes, it only increase or decrease the number of unit current source which is be chosen. This approach can reach a better static performance than full random DEM technique but also eliminate signal dependent distortions to achieve good linearity at high sampling frequencies as other DEM implementations.
