Ultra-Low-Power Short-Range Radios

Abstract

This book explores the design of ultra-low-power radio-frequency integrated circuits (RFICs), with communication distances ranging from a few centimeters to a few meters. Such radios have unique challenges compared to longer-range, higher-powered systems. As a result, many different applications are covered, ranging from body-area networks to transcutaneous implant communications and Internet-of-Things devices. A mix of introductory and cutting-edge design techniques and architectures which facilitate each of these applications are discussed in detail. Specifically, this book covers. Introduction to Ultra Low Power Transceiver Design -- Channel Modeling for Wireless Body Area Networks -- Circuit Techniques for Ultra-Low Power Radios -- Architectures for ultra-low-power multi-channel resonator-based wireless transceivers -- Ultra-Low Power Wake-Up Radios -- Commercially Viable Ultra-Low Power Wireless -- Synchronization clocks for ultra-low power wireless networks -- Pulsed Ultra-Wideband Transceivers -- Human Body Communication Transceiver for Energy Efficient BAN -- Centimeter-Range Inductive Radios -- Near-Field Wireless Power Transfer -- Energy Harvesting Opportunities for Low-Power Radios.
