A delta-sigma modulator comprising a number of integration stages and having a feed-forward path from a signal input section to the signal path prior to a final integration stage, so as to reduce processing in the majority of integration stages to error processing. A delta-sigma modulator with acceptable dynamic range and incomplete settling can be designed for audio applications using a ratio of gain bandwidth product to sampling frequency in terms of a resolution of the converter. Satisfying the criteria provided by the ratio reduces the gain bandwidth requirement below that previously used as acceptable values in data converter design.
