Dynamic element matching原理
WebA Dynamic Element Matching Technique for Reduced-Distortion Multibit Quantization in Delta–Sigma ADCs Eric Fogleman, Member, IEEE, and Ian Galton, Member, IEEE … 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 …

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. biman bangladesh airlines banani officeWeblinearity 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.
