Delta-Sigma A/D Converters
Delta-Sigma Modulator A/D Converters are a class of Oversampled Data-Converters which have been used commercially in the past ten years as a viable alternative for Nyquist-rate converters (such as Flash,SAR,Pipelined ADCs etc). The preference for Delta-Sigma A/D Converter is because of the reduced Quantization Noise in the band of interest due to OSR and the feedback loop.
