The author examines the practical design criteria for implementing oversampled analog/digital converters based on second-order sigma-delta ( Sigma Delta ) modulation.Expand

An experimental technique is described for observing the effects of switching transients in digital MOS circuits that perturb analog circuits integrated on the same die by means of coupling through the substrate.Expand

Oversampling and feedback can be employed in high-resolution /spl Sigma//spl Delta/ modulators to extend the signal bandwidth into the range of several megahertz when the oversampling ratio is constrained by technology limitations.Expand
