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:
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. The authors describe leading-edge techniques to achieve ultra-low-power communication over short-range links. Many different applications are covered, ranging from body-area networks to transcutaneous implant communications and smart-appliance sensor networks. Various design techniques are explained to facilitate each of these applications. Ultra-low-power RFIC design concepts and techniques over a wide variety of applications Channel modeling for both wireless and body-coupled communication in body-area networks Narrowband, wideband and human-body channel RF front-ends Ultra-low-power timers and network synchronization schemes Wireless power transfer and energy harvesting to support the energy needs of the underlying radio systems Includes supplementary material: sn.pub/extras
