Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in home healthcare, environmental sensing, and low power computing have created a need for wireless communication at very low power for low data rate applications. Due to higher energy/bit requirements at lower data -rate, achieving power levels low enough to enable long battery lifetime (~10 years) or power-harvesting supplies have not been possible with traditional approaches. Dutycycled radios have often been proposed in literature as a solution for such applications due to their ability to shut off the static power consumption at low data rates. While earlier radio nodes for such systems have been proposed based on a type of sleepwake scheduling, such implementations are still power hungry due to large synchronization uncertainty (~1[MICRO SIGN]s). In this dissertation, we utilize impulsive signaling and a pulse-coupled oscillator (PCO) based synchronization scheme to facilitate a globally synchronized wireless network. We have modeled this network over a widely varying parameter space and found that it is capable of reducing system cost as well as providing scalability in wireless sensor networks. Based on this scheme, we implemented an FCC compliant, 3-5GHz, timemultiplexed, dual-band UWB impulse radio transceiver, measured to consume only 20[MICRO SIGN]W when the nodes are synchronized for peer-peer communication. At the system level the design was measured to consume 86[MICRO SIGN]W of power, while facilitating multi- hop communication. Simple pulse-shaping circuitry ensures spectral efficiency, FCC compliance and ~30dB band-isolation. Similarly, the band-switchable, ~2ns turn-on receiver implements a non-coherent pulse detection scheme that facilitates low power consumption with -87dBm sensitivity at 100Kbps. Once synchronized the nodes exchange information while duty-cycling, and can use any type of high level network protocols utilized in packet based communication. For robust network performance, a localized synchronization detection scheme based on relative timing and statistics of the PCO firing and the timing pulses ("sync") is reported. No active hand-shaking is required for nodes to detect synchronization. A self-reinforcement scheme also helps maintain synchronization even in the presence of miss-detections. Finally we discuss unique ways to exploit properties of pulse coupled oscillator networks to realize novel low power event communication, prioritization, localization and immediate neighborhood validation for low power wireless sensor applications.

This book was released on 2010-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultra-wideband (UWB) impulse-radio technology has unique features including high data-rate as well as low power consumption with ranging and localization capabilities. An UWB front-end, however, has to accommodate design challenges resulting from the exceptional wide bandwidth of several GHz. This book discusses the implementation issues of the UWB impulse-radio transceiver front-end, including the performance analysis of practical systems and the design of radio-frequency integrated circuits for transceiver front-ends. A general framework for performance evaluation of practical impulse radio system is proposed and demonstrated in scenarios of high-speed data communications as well as low-data-rate wireless body-area networks. An inductorless low- noise amplifier is designed with syncretic adoption of thermal noise canceling, capacitor peaking, and current reuse. The CMOS ransmit/receive switch design with highest reported bandwidth and power handling capability are discussed with customized transistor layout and triple-well resistive body- floating techniques. The prototypes have been demonstrated in state-of-the-art 130nm CMOS technology.

Book Synopsis Energy Scalable Radio Design by : Marian Verhelst
Download or read book Energy Scalable Radio Design written by Marian Verhelst and published by Springer Science & Business Media. This book was released on 2009-07-14 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart energy management, both at design time and at run time, is indispensable in modern radios. It requires a careful trade-off between the system’s performance, and its power consumption. Moreover, the design has to be dynamically reconfigurable to optimally balance these parameters at run time, depending on the current operating conditions. Energy Scalable Radio Design describes and applies an energy-driven design strategy to the design of an energy-efficient, highly scalable, pulsed UWB receiver, suitable for low data rate communication and sub-cm ranging. This book meticulously covers the different design steps and the adopted optimizations: System level air interface selection, architectural/algorithmic design space exploration, algorithmic refinement (acquisition, synchronization and ranging algorithms) and circuit level (RTL) implementation based on the FLEXmodule-concept. Measurement results demonstrate the effectiveness and necessity of the energy-driven design strategy.

Book Synopsis Ultra Low-Power Biomedical Signal Processing by : Sandro Augusto Pavlik Haddad
Download or read book Ultra Low-Power Biomedical Signal Processing written by Sandro Augusto Pavlik Haddad and published by Springer Science & Business Media. This book was released on 2009-05-26 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Often WT systems employ the discrete wavelet transform, implemented on a digital signal processor. However, in ultra low-power applications such as biomedical implantable devices, it is not suitable to implement the WT by means of digital circuitry due to the relatively high power consumption associated with the required A/D converter. Low-power analog realization of the wavelet transform enables its application in vivo, e.g. in pacemakers, where the wavelet transform provides a means to extremely reliable cardiac signal detection. In Ultra Low-Power Biomedical Signal Processing we present a novel method for implementing signal processing based on WT in an analog way. The methodology presented focuses on the development of ultra low-power analog integrated circuits that implement the required signal processing, taking into account the limitations imposed by an implantable device.

This book was released on 2015-07-25 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with a state-of-the-art description of techniques to be used for ultra-low-power (ULP) and ultra-low-cost (ULC), short-range wireless receivers. Readers will learn what is required to deploy these receivers in short-range wireless sensor networks, which are proliferating widely to serve the internet of things (IoT) for “smart cities.” The authors address key challenges involved with the technology and the typical tradeoffs between ULP and ULC. Three design examples with advanced circuit techniques are described in order to address these trade-offs, which special focus on cost minimization. These three techniques enable respectively, cascading of radio frequency (RF) and baseband (BB) circuits under an ultra-low-voltage (ULV) supply, cascading of RF and BB circuits in current domain for current reuse and a novel function-reuse receiver architecture, suitable for ULV and multi-band ULP applications such as the sub-GHz ZigBee.

This book was released on 2013-03-28 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011-10 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short-range wireless communications continually attract interest from both industry and academia, and it is changing our life in every aspect in the last decade. The design of wireless transceivers is the bottleneck for a variety applications, due to RF modeling inaccuracy, stringent FCC regulations over the transmitted power spectrum, interference, multi-path reections, modulation scheme, receiver sensitivity, and synchronization. In addition, energy efficiency is always one of the most important design goals. Ultra-Wideband(UWB) is found to be very energy-efficient due to its low duty cycle and potentially high data rate due to its wide bandwidth. However, there still remain unsolved issues with UWB transceivers, such as pulse shaping, multi-path re ections, and receiver clock synchronization. To address these, novel techniques such as wireless multi-path equaliza- tion, pulse injection-locking for receiver clock synchronization, reconfigurable pulse shaping, low power wireless clock distribution, and an ultra-low-power super- regenerative receiver are implemented and verified on silicon. Three chips are designed and verified: a 3-5GHz Impulse-Radio(IR) UWB transceiver, a 3-60GHz al

Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, ultra wideband (UWB) systems gained a large interest in the scientific world because of their suitability to realize among others communication systems with tremendous data rates and accurate indoor positioning and location systems. As a differing technology compared to classical narrowband radio transmission systems, UWB requires some novel approaches. Well established methods to develop and analyze narrowband transmission systems remain essentially valid but are not always well tailored or optimal to UWB systems. The need for novel approaches illuminates the reasons why there are still some uncovered topics in the literature, mainly related to the analyses of imperfections and perturbations during an UWB transmission. Consequently, this thesis attempts to cover some of these topics by theoretical studies, numerical simulations, as well as experimental verification.
