  • Method for calibrating a digital/analog converter and digital/analog converter
    Patent number: 7372383
    Abstract: A digital/analog converter comprises a converter array comprised of a plurality of converter cells and a device for self-calibration of the converter cells. The device for self-calibration comprises at least one reference cell with a reference value and a control device for controlling a calibration process. The control device calibrates successively, within a respective calibration period, respective of the converter cells to values corresponding to the reference value and adjusts respective calibration periods for a calibration cycle, within which the converter cells are to be calibrated. At least two different of the respective calibration periods differ within at least two calibration cycles.

  • Method for digital/analog conversion and corresponding digital/analog converter device
    Patent number: 7199741
    Abstract: A method and a device for digital/analog conversion are proposed, whereby for improved use of a “dynamic element matching” algorithm, in particular a “data weighted averaging” algorithm, the number of existing conversion elements is greater than a maximum number of possible input or control codes for the conversion elements (7), that is to say greater than a number of conversion elements, which would actually be necessary for a maximum value of the digital word to be converted in each case.
