  • Abstract
    Two new start-up DAC calibration techniques are proposed for double-sampling DeltaSigma modulators. The first one is a modification of the existing calibration technique, while the second technique is proposed specifically for double-sampling DeltaSigma modulators. Dynamic element matching is used to eliminate "intra-DAC" mismatches, and digital correction for the remaining "inter-DAC" mismatches.
