  • Calibration method for redundant A/D and D/A converters with a weighted network
    Patent number: 4970514
    Abstract: A calibration method for redundant A/D and D/A converters with a weighted network and error correction includes performing a self-calibration in which each of n weighted elements is determined as a function of respectively lower weighted elements by means of a measurement with n steps, except for a lowest weighted element. Subsequently each weighted element is calculated and stored in memory in terms of the sum of all of the weighted elements as a function of the results of the measurement with the aid of a calculating register.
