It shows readers how to develop power-efficient complementary-metal-oxide-semiconductor (CMOS) ADCs for applications such as LTE, 802.11n, and VDSL2+. The material covered can also be applied to other specifications and technologies. Design of Power-Efficient Highly Digital Analog-to-Digital Converters for Next-Generation Wireless Communication Systems begins with a general introduction to the applications of an ADC in communications systems and the basic concepts of VCO-based ADCs. The text addresses a wide range of converter architectures including open- and closed-loop technologies. Special attention is paid to the replacement of power-hungry analog blocks with VCO-based circuits and to the mitigation of VCO nonline arity. Various MATLAB®/Simulink® models are provided for important circuit nonidealities, allowing designers and researchers to determine the required specifications for the different building blocks that form the systematic integrated-circuit design procedure. Five different VCO-based ADC design examples are presented, introducing innovations at both architecture and circuit levels. Of these designs, the best power efficiency of a high-bandwidth oversampling ADC is achieved in a 40 nm CMOS demonstration. This book is essential reading material for engineers and researchers working on low-power-analog and mixed-signal design and may be used by instructors teaching advanced courses on the subject. It provides a clear overview and comparison of VCO-based ADC architectures and gives the reader insight into the most important circuit imperfections.Signals and Communication Technology,1860-4862Electronic circuitsElectrical engineeringEnergy consumptionCircuits and Systemshttps://scigraph.springernature.com/ontologies/product-market-codes/T24068Communications Engineering, Networkshttps://scigraph.springernature.com/ontologies/product-market-codes/T24035Energy Efficiencyhttps://scigraph.springernature.com/ontologies/product-market-codes/118000Electronic circuits.Electrical engineering.Energy consumption.Circuits and Systems.Communications Engineering, Networks.Energy Efficiency.621.39814Xing Xinpengauthttp://id.loc.gov/vocabulary/relators/aut1059949Zhu Pengauthttp://id.loc.gov/vocabulary/relators/autGielen Georgesauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910299879603321Design of Power-Efficient Highly Digital Analog-to-Digital Converters for Next-Generation Wireless Communication Systems2509788UNINA
