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 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 … earbuds low profile

WebA high-accuracy CMOS temperature sensor with integrated bus interface is presented. It is shown that when offset cancellation and dynamic element matching techniques are applied, the accuracy of the sensor is mainly limited by process spread between batches on the substrate bipolar transistors. Therefore, the sensors can be calibrated per batch …
