Book Description
Inhaltsangabe:Abstract: The Bluetooth wireless technology is the worlds new short-range RF transmission standard for small form factor, low-cost, short-range radio links between portable or desktop devices. The technology promises to eliminate the confusion of cables, connectors and protocols confounding communications between today high tech products. In the first step a 2.45 GHz Low Noise Amplifier (LNA), intended for use in a Bluetooth receiver, has been designed in a standard 0.18 um CMOS process. The amplifier provides a simulated switchable forward voltage gain of +16 / -7.7 dB with a simulated noise Figure (NF) of only 3 dB while drawing 2.8 mA from a 1.8 V supply. The die area of the LNA (pads included) is 0.79 mm2. In the second step a 2.45 GHz Power Amplifier (PA), also intended for the Bluetooth standard, has been designed in the same 0.18 um CMOS process as for the LNA. The class-A PA achieves a simulated forward gain (S21) of 23 dB and a simulated output 1 dB compression point (P1dB ) of 5.5 dBm, with a power-added efficiency (PAE) of 23 % while drawing 15.8 mA from a 1.8 V supply. The die area of the PA (pads included) is 2.1 mm2.

Ultra Low Power Transceiver for Wireless Body Area Networks
Author: Jens Masuch
Publisher: Springer Science & Business Media
ISBN: 3319000985
Category : Technology & Engineering
Languages : en
Pages : 126
Book Description
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.

Pages : 204
Book Description
This book is dedicated to the analysis of parametric amplification with special emphasis on the MOS discrete-time implementation. This implementation is demonstrated by the presentation of several circuits where the MOS parametric amplifier cell is used: small gain amplifier, comparator with embedded pre-amplification, discrete-time mixer/IIR-Filter, and analog-to-digital converter (ADC). Experimental results are shown to validate the overall design technique.

Digital Radio System Design
Author: Grigorios Kalivas
Publisher: John Wiley & Sons
ISBN: 9780470748374
Category : Technology & Engineering
Languages : en
Pages : 472
Book Description
A systematic explanation of the principles of radio systems, Digital Radio System Design offers a balanced treatment of both digital transceiver modems and RF front-end subsystems and circuits. It provides an in-depth examination of the complete transceiver chain which helps to connect the two topics in a unified system concept. Although the book tackles such diverse fields it treats them in sufficient depth to give the designer a solid foundation and an implementation perspective. Covering the key concepts and factors that characterise and impact radio transmission and reception, the book presents topics such as receiver design, noise and distortion. Information is provided about more advanced aspects of system design such as implementation losses due to non-idealities. Providing vivid examples, illustrations and detailed case-studies, this book is an ideal introduction to digital radio systems design. Offers a balanced treatment of digital modem and RF front-end design concepts for complete transceivers Presents a diverse range of topics related to digital radio design including advanced transmission and synchronization techniques with emphasis on implementation Provides guidance on imperfections and non-idealities in radio system design Includes detailed design case-studies incorporating measurement and simulation results to illustrate the theory in practice
