Noise-Shaping in Data Converters Slides & Transcript

Abstract - Noise shaping is a powerful technique that helps improve the overall accuracy of a data converter. While this technique is widely used in the context of delta sigma modulators, noise shaping is also gaining popularity in other kinds of converters such as SARs. This tutorial will present the fundamentals of noise shaping along with the architectural view of their application in different data converters such as ?? modulators and SARs. Circuit implementation of key building blocks along with challenges in realization and their mitigation strategies will be discussed as well.
