SYSTEM AND METHOD FOR DYNAMIC ELEMENT MATCHING FOR DELTA SIGMA CONVERTERS

Abstract:

Systems and methods for improving the efficiency of a rotational dynamic element matching (DEM) for Delta Sigma converters. In some implementations, the systems and methods are provided a for reducing intersymbol interference (ISI) of a Delta Sigma converter. A delta sigma converter architecture can include multiple I-DACs, and the output from each I-DAC can vary from the other I-DACs. Techniques are disclosed for decreasing mismatch among multiple I-DACs while improving efficiency of rotational dynamic element matching.
