- 20 - ABSTRACT A sigma-Delta converter, comprising means for receiving an input digital signal; a digital loop filter and quantizer having an input and an output; a summer having a first input connected to the means for receiving, a second input connected to the output of the digital loop filter and quantizer, and an output connected to the input of the digital loop filter and quantizer for subtracting from the input digital signal an output digital signal from the digital loop filter and quantizer, and in response generating a difference signal for application to the input of the digital loop filter and quantizer; and digital-to- analog converter having a plurality of unit elements with minor mismatching therebetween, for receiving and converting to analog the output digital signal from the digital loop filter and quantizer, and in response generating an output analog signal, where the digital-to- analog converter comprises means for cyclically selecting successive difference permutations of the unit elements for converting each value of the output digital signal thereby cancelling the mismatching between unit elements.
