ABSTRACT:
An analog-to-digital converter circuit arrangement comprising an analog-to-digital converter that receives an analog input signal and provides a digital output signal. A correction device that corrects the digital output signal using multidimensional correction coefficients indicative of a characteristic of the analog-to-digital converter to be compensated for, and provides a corrected digital output signal indicative thereof.
