Two digital techniques are described in this tutorial, both aimed at improving the accuracy of delta-sigma data converters. The first one corrects adaptively for mismatch errors in a MASH ADC, while the other acquires and then corrects for the nonlinearity of the internal multibit DAC used in the ADC.
