    Abstract: Aspects of a method and apparatus for converting an analog input value to a digital output code are provided. One embodiment of the apparatus includes a digital-to-analog converter, a comparator, and control logic circuitry. The digital-to-analog converter is configured to generate an analog reference value based on a received digital reference value. The comparator is configured to compare an analog input value to the analog reference value after expiration of an allotted settling time for the digital-to-analog converter and generate a comparison result indicative a relationship between the analog input value and the analog reference value. The control logic circuitry is configured to select the allotted settling time for the digital-to-analog converter based on a bit position of a digital output code to be determined, and update the bit position of the digital output code based on the comparison result.

    Abstract: Systems and methods are provided for digital-to-analog converters (DACs) with enhanced dynamic element matching (DEM) and calibration. DEM may be adapted based on assessment of one or more conditions that may affect the DACs or DEM functions thereof. The one or more condition may comprise amount of signal backoff. The adaption may comprise switching the DEM function (as a whole, or partially—e.g., individual DEM elements) on or off based on the assess conditions. The DACs may incorporate use of calibration. The DEM and/or the calibration may be applied to only a portion of the DAC, such as a particular segment (e.g., a middle segment comprising bits between the MSBs and the LSBs).
