Claim 12:
13. A digital-to-analog conversion method for converting a multi-bit word representing an integer within a range of integers to an analog feedback signal of an incremental analog-to-digital converter, iADC, the digital-to-analog conversion method comprising
generating a selection vector with a predefined number of bits based on the multi-bit word,
generating, with a plurality of output elements,, respective analog portions based on the selection vector,
combining the analog portions to the analog feedback signal,, wherein the generation of the selection vector comprises
successive splitting of the multi-bit word into portions and sub-portions, respectively,
adjusting of weight factors by multiplying the weight factors with the difference of two respective sub-portions, and
accumulating successive adjusted weight factor, wherein the way of splitting portions of further multi-bit words at subsequent clock periods within the conversion cycle of the iADC is determined based on the sign of the accumulation of adjusted weight factors.
