Download Ultra-Low Power FM-UWB Transceivers for IoT Book in PDF, Epub and Kindle
Over the past two decades we have witnessed the increasing popularity of the internet of things. The vision of billions of connected objects, able to interact with their environment, is the key driver directing the development of future communication devices. Today, power consumption as well as the cost and size of radios remain some of the key obstacles towards fulfilling this vision. Ultra-Low Power FM-UWB Transceivers for IoT presents the latest developments in the field of low power wireless communication. It promotes the FM-UWB modulation scheme as a candidate for short range communication in different IoT scenarios. The FM-UWB has the potential to provide exactly what is missing today. This spread spectrum technique enables significant reduction in transceiver complexity, making it smaller, cheaper and more energy efficient than most alternative options. The book provides an overview of both circuit-level and architectural techniques used in low power radio design, with a comprehensive study of state-of-the-art examples. It summarizes key theoretical aspects of FM-UWB with a glimpse at potential future research directions. Finally, it gives an insight into a full FM-UWB transceiver design, from system level specifications down to transistor level design, demonstrating the modern power reduction circuit techniques. Ultra-Low Power FM-UWB Transceivers for IoT is a perfect text and reference for engineers working in RF IC design and wireless communication, as well as academic staff and graduate students engaged in low power communication systems research.

Download Wideband FM Techniques for Low-Power Wireless Communications Book in PDF, Epub and Kindle
Ultra Wideband (UWB) communications are poised to enable short-range applications, such as remote health monitoring (e-health) and home or office automation. Sensor networks are also suitable candidates for UWB since the low radiated power of the UWB transmitter enables low DC power consumption, yielding long battery life and the possibility to use energy scavenging. Size and cost constraints require a low-complexity approach that allows multiple users to share the same RF bandwidth, and offers robustness to interference, frequency-selective multipath and antenna mismatch. Wideband FM Techniques for Low-Power Wireless Communications presents research and applications that have taken place in UWB Communications over the past years. This book is being published posthumously in agreement with the authors’ former colleagues from both the Swiss Center for Electronics and Microtechnology (CSEM) and Delft University of Technology in The Netherlands.

Download Ultra Low Power Transceiver for Wireless Body Area Networks Book in PDF, Epub and Kindle
Wireless Body Area Networks (WBANs) are expected to promote new applications for the ambulatory health monitoring of chronic patients and elderly population, aiming to improve their quality of life and independence. These networks are composed by wireless sensor nodes (WSNs) used for measuring physiological variables (e.g., glucose level in blood or body temperature) or controlling therapeutic devices (e.g., implanted insulin pumps). These nodes should exhibit a high degree of energy autonomy in order to extend their battery lifetime or even make the node supply to rely on harvesting techniques. Typically, the power budget of WSNs is dominated by the wireless link and, hence, many efforts have been directed during the last years toward the implementation of power efficient transceivers. Because of the short range (typically no more than a few meters) and low data rate (typically in between 10 kb/s and 1 Mb/s), simple communication protocols can be employed. One of these protocols, specifically tailored for WBAN applications, is the Bluetooth low energy (BLE) standard. This book describes the challenges and solutions for the design of ultra-low power transceivers for WBANs applications and presents the implementation details of a BLE transceiver prototype. Coverage includes not only the main concepts and architectures for achieving low power consumption, but also the details of the circuit design and its implementation in a standard CMOS technology.

Download Ultra-Wideband Transceiver Circuits and Systems Book in PDF, Epub and Kindle
Wideband radio technology is not a new concept in the field of RF technology. Decades of research in the area of wideband systems has lead us to new possibilities in the design of low-power, low complexity radios. Ultra-wideband is a direct offspring, which takes the initiative a step further by presenting novel wideband techniques for RF technology. The US FCC position on UWB for commercial usage changed after agreeing to adopt the First Report and Order on February 14, 2002. Unlicensing several gigahertz of frequency spectrum allowed companies to manufacture and market products incorporating UWB technology. At a certain moment, the potential benefits of UWB were outweighed, when existing wireless (narrowband) regulators perceived UWB as a disruptive influence. This, however, did not stop most countries from accommodating and recognizing the true nature of UWB. In brief, the authors have only scratched the surface when it comes to understanding the true potential of UWB technology. The development stage is in its infancy and will necessitate a substantial amount of research to meet industrial specifications. Short-range communications, low-power and low/moderate data rate throughput are the most attractive aspects and promises of UWB technology. For this very reason, applications, such as wireless sensor networks (WSN) are most noticeable.

Download A Low Power Ultra Wideband Transceiver and Sensor Interface Architecture for Wireless Sensor Networks Book in PDF, Epub and Kindle
"This thesis focuses on the design of a low power ultra wideband (UWB) transceiver and a low power sensor interface architecture, both for use in wireless sensor networks.Pulse-based UWB radios communicate using short broadband pulses, which allow the transceiver to be duty cycled such that power is only consumed when a pulse is being transmitted or received. This enables increased power savings when compared to traditional narrowband transceivers. The receiver designed here is based on peak detection, and it is shown that this type of non-coherent receiver can perform better than a more complex energy detection receiver in interference dominated environments (such as urban areas) in both an additive white Gaussian noise channel, and a multipath environment.The fabricated UWB receiver uses a clock and data recovery system to synchronize the local receiver clock to the transmitted data to reduce synchronization time and enable more efficient communications for sensor networks, which typically have a small data payload. By moving the synchronization to the analog domain, the size and power consumption of the digital backend is reduced significantly when compared to other receiver architectures. The clock and data recovery synchronization scheme also provides real time tracking of any variations in the transmitted data rate and the receiver clock, which minimizes the need for a high precision crystal reference in either system. The fabricated UWB transmitter is implemented by exciting a pulse shaping filter with a broadband pulse, and the resulting signal conforms to the FCC spectral mask including the GPS stopband. The demonstrated transceiver system achieves a sensitivity of -66.5 dBm with a power consumption of ~400 [mu]W at a 1 Mbps data rate, making it suitable for wireless sensor networks and other low power, low data rate systems.An architecture for an energy efficient sensor interface for frequency domain sensors is also presented. The proposed system produces a digital output with inherent temperature compensation without the need for a high accuracy temperature sensor, a heater, or a temperature insensitive clock. This architecture is targeted towards systems where the emphasis is placed on battery longevity as opposed to high resolution sensing, such as in wireless sensor nodes." --
