Abstract
An analog-to-digital converter (). The analog to digital converter () comprises a first range-control unit () adapted to generate a first range-control value for controlling a size of an input range of the analog-to-digital converter (). The analog to digital converter further comprises a second range-control unit () adapted to generate a second range-control value for controlling a midpoint of the input range. Further, the analog-to-digital converter () comprises a reference-level unit () operatively connected to the first range-control unit () and the second range-control unit (). The reference-level unit () is arranged to generate a plurality of reference levels at least based on the first and the second range-control value. The analog-to-digital converter further comprises a comparison unit () operatively connected to the second range-control unit () and the reference-level unit (). The comparison unit () is arranged to perform at least one comparison between a difference between an analog input value of the analog-to-digital converter () and the second range-control value and individual reference levels of the plurality of reference levels. The comparison unit () is further arranged to generate a digital output value of the analog-to-digital converter () based on the at least one comparison.
