Charge-Sharing SAR ADCs for Low-Voltage Low-Power Applications [Paperback]

This book introduces readers to the potential of charge-sharing (CS) successive approximation register (SAR) analog-to-digital converters (ADCs), while providing extensive analysis of the factors that limit the performance of the CS topology. The authors present guidelines and useful techniques for mitigating the limitations of the architecture, while focusing on the implementation under restricted power budgets and voltage supplies.

Introduction.- ADCs for Low Voltage Low Power Applications.- Review of SAR ADC Switching Schemes.- Analysis of the charge sharing SAR ADC topology.- Techniques for Low Voltage Low Power CS SAR ADCs.- Noise-aware comparator optimization.- CS ADCs with MOSCAP-based DACs.- Design and Implementation of two Low-Voltage SAR ADCs.- Conclusion.

Taimur Rabuske was born in Rio Grande do Sul, Brazil. He received the B.Sc. and M.Sc. degrees in Electrical Engineering and Computer Sciences from Universidade Federal de Santa Maria (UFSM), Brazil, in 2009 and 2011, respectively, and the Ph.D. degree (with distinction and honour) in Electrical and Computer Engineering from Instituto Superior T?cnico, Portugal, in 2016. From July to December 2009, he was an intern at Gwangju Institute of Science and Technology (GIST), South Korea, and from July 2010 to June 2016 he was a research assistant at INESC-ID, Lisbon, Portugal. His current research interests include design and optimization of RF, analog and mixed-signal circuits, data converters, techniques for ultra-low power and design methodologies.

Jorge Fernandes was born in Lisbon in 1966. He received the Degree in electrical engineering from the Instituto Superior T?cnico (IST), Universidade de Lisboa, Portugal, in 1989, and the M.Sc., Ph.D., and Habilitation degrees from the same university in 1993, 2000, and 2010, respectively. He joined the teaching staff of the Department of Electrical Engineering at IST, in 1989,l£_
