Abstract
The control apparatus (8′) is used to dynamically assign N individual references to N individual comparators of a quantizer in a sigma-delta analogue/digital converter, the control apparatus (8′) generating a digital control signal (9′). The control apparatus (8′) has a storage means (12) for providing the value of the control signal (9′) at the time k−1, and a summation means (10) for summing the output signal Y of the quantizer with the stored value of the first control signal (9′) at the time k−1.
