Dynamic element matching原理

Webby mismatches among nominally identical circuit elements inevitably introduced during circuit fabrication. It is assumed that the mismatch errors do not significantly change … WebThe dynamic element matching (DEM) techniques for digital-to-analog converters (DACs) has been suggested as a promising method to improve matching between the DAC's referencelevels. However, no work has so far taken the dynamic effects that limit the performance for higher frequenciesinto account. In this paper we present a model …
