Delta-sigma A/D converters: the next generation

Delta-sigma A/D converters are well suited for applications requiring high resolution in a relatively low frequency bandwidth. As the technology continues to mature, the next generation of delta-sigma A/D converters will be exploited for applications requiring both high resolution and high speed. This paper describe three approaches to extending the useful bandwidth of the delta-sigma A/D converter. They include the use of multibit quantization with feedforward digital compensation, multibit quantization with feedback dynamic element matching and the use of parallelism
