WebJan 1, 2003 · The dynamic element matching (DEM) techniques for digital-to-analog converters(DACs) has been suggested as a promising method to improve matching … WebPTAT voltages. Furthermore, it is shown that dynamic element matching and auto-calibration can solve the problems related to mismatching of components and 1 noise. The effects of mechan-ical stress are a major source of inaccuracy. In CMOS technology, the mechanical-stress effects are small, as compared to those in bipolar technology. how heavy is derrick henry
