Abstract
A method of determining at least one calibration value for a redundant analog-to-digital-converter, ADC, is disclosed. For at least an i:th bit bL, the corresponding bit weight wis less than the sum of the bit weights W, j=0, 1, . . . , i−1 corresponding to the bits b, j=0, 1, . . . , i−1 with lesser significance than the bit bi. The method comprises sampling a first electrical value representative of the bit weight w; performing a first analog-to-digital, A/D, conversion using the bits b, j=0, 1, . . . , i−1 with lesser significance than the bit bto obtain a first digital word of said bits b, j=0, 1, . . . , i−1 with lesser significance than the bit brepresenting said first electrical value; and estimating the value of the bit weight Wexpressed in terms of the bit weights Wj. j=0, 1, . . . , i−1 corresponding to the bits b, j=0, 1, . . . , i−1 with lesser significance than the bit bbased at least on said first digital word, wherein the resulting estimated value of the bit weight wis one of the at least one calibration value. A control unit, a redundant ADC and a computer program are also disclosed.
