Dissecting Design Choices in Continuous-time Delta-Sigma Converters Slides

Abstract - Continuous-time Delta-Sigma Modulators (CTDSMs) are a compelling choice for the design of high resolution analog-to-digital converters. Many delta-sigma architectures have been published (and continue to be invented). This leaves the designer with a bewildering array of choices, many of which seem to pull in opposite directions. Further, it is often difficult to make a clear comparison of various architectures, as they have been designed for dissimilar specifications, by different design groups, and in different technology nodes. This talk examines various alternatives for the design of power efficient single-loop continuous-time delta sigma converters.
