Session 27 overview / data converters: Oversampling converters

Summary form only given. Oversampling delta-sigma (ΔΣ) data converters are widely used for high-resolution A/D and D/A conversions of low-to-medium bandwidth signals with applications ranging from sensor networks and audio interfaces to wireless communications. The performance of these converters is advancing in several fronts including resolution, bandwidth and power efficiency. This session presents papers that highlight such advancements to unprecedented levels, including continuous-time (CT) ΔΣ A/D converters with signal bandwidths up to 125MHz, discrete-time (DT) ΔΣ A/D converters with power efficient architecture and functional blocks, and audio ΔΣ D/A converters with improved accuracy-enhancement methods.
