The proposed technique can address er … WebGenerally speaking: dynamic element matching can be used advantageously in those cases where a network consists of or can be divided into a number of nearly equal elements. An improvement in overall accuracy can be obtained by a continu-ous and cyclic interchange of these nearly equal elements. The average value of the output signals is a …

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 … Weblinearity is severely limited by the matching of elements. Process lithography provides elements with a typical matching of 0.1-0.5% corresponding to a resolution of 8-lobits. Higher resolutions can be obtained by laser trimming or digital calibration techniques [3-41. However, an attractive solution due to
