Описание:
While mobile phones enjoy the largest production volume ever of any consumer electronics products, the demands they place on radio-frequency (RF) transceivers are particularly aggressive, especially on integration with digital processors, low area, low power consumption, while being robust against process-voltage-temperature variations. Since mobile terminals inherently operate on batteries, their power budget is severely constrained. To keep up with the ever increasing data-rate, an ever-decreasing power per bit is required to maintain the battery lifetime. The RF oscillator is the second most power-hungry block of a wireless radio (after power amplifiers). Consequently, any power reduction in an RF oscillator will greatly benefit the overall power efficiency of the cellular transceiver. Moreover, the RF oscillators' purity limits the transceiver performance. The oscillator's phase noise results in power leakage into adjacent channels in a transmit mode and reciprocal mixing in a receive mode. On the other hand, the multi-standard and multi-band transceivers that are now trending demand wide tuning range oscillators. However, broadening the oscillator's tuning range is usually at the expense of die area (cost) or phase noise.
The main goal of this book is to bring forth the exciting and innovative RF oscillator structures that demonstrate better phase noise performance, lower cost, and higher power efficiency than currently achievable.
Technical topics discussed in RF CMOS Oscillators for Modern Wireless Applications include:
- Design and analysis of low phase-noise class-F oscillators - Analyze a technique to reduce 1/f noise up-conversion in the oscillators - Design and analysis of low power/low voltage oscillators - Wide tuning range oscillators - Reliability study of RF oscillators in nanoscale CMOS
Описание: The revolution in wireless communication technology was initiated in the nineties, leading to the development of new mobile communication systems including GSM, GPRS, EDGE, WCDMA, WLAN, HSDPA, WiMAX and recently LTE-Advanced. These technologies have revolutionized the way and manner modern communication is undertaken. The revolution is not only in network design but also in new devices, handsets and Internet enabled devices. It is impossible for these technologies to be created without the support of other fields such as advanced signal processing techniques including OFDM, MIMO, coding, voice, image and video compression. These developments have also created the migration in focus from fixed telephony to IP telephony with complimentary consequences in the use of social networking and online retail and sales. As welcome as the new developments are, the overwhelming depth of technical expertise required to understand and follow the progress in technology advancement makes it harder and harder for the telecommunication engineer to follow without a logical and detailed compendium of the major concepts leading to these advancements.This book is a detailed compendium of these major advancements focusing exclusively on the emerging broadband wireless communication technologies which support broadband wireless data rate transmissions. Several applications of the wireless communication networks including health care, underground communication, biomedical and bio-telemetry systems are detailed in the book. Technical topics:Cellular communication concepts.CDMA, WCDMA, WiMAX, LTE-Advanced and Zigbee.Fading, diffraction and propagation models.Block and error control coding in modern communication networks including msequences, OVSF, Gold and Golay codes.OFDM and MIMO.Multi-carrier and cooperative communication techniques.Applications of wireless communication networks.Optical networks.Electromagnetic interference.
