<p>An A/D converter has an input part IS which provides transitions T1..Tx associated with different levels of an analog input signal Vin. An intermediate part IMS carries out folding and interpolation operations F1, I1 and F2, I2..IN on the transitions T1..Tx to obtain a set of bit-determining signals XO.. XQ. At least one of the operations, folding F1, F2,.. or interpolation I1, IN, is carried out more than once in alternation with the other operation, interpolation I1, IN or folding F1, F2,.. respectively. An output part OS provides a digital output signal Do on the basis of the bit-determining signals XO..XQ. Such an A/D converter can be implemented in a cost-efficient manner and may be combined with digital signal-processing circuitry.</p> |
