Feedback Linearization of RF Power Amplifiers by J.L. Dawson,Thomas H. Lee Pdf

Improving the performance of the power amplifier is the most pressing problem facing designers of modern radio-frequency (RF) transceivers. Linearity and power efficiency of the transmit path are of utmost importance, and the power amplifier has proven to be the bottleneck for both. High linearity enables transmission at the highest data rates for a given channel bandwidth, and power efficiency prolongs battery lifetime in portable units and reduces heat dissipation in high-power transmitters. Cartesian feedback is a power amplifier linearization technique that acts to soften the tradeoff between power efficiency and linearity in power amplifiers. Despite its compelling, fundamental advantages, the technique has not enjoyed widespread acceptance because of certain implementation difficulties. Feedback Linearization of RF Power Amplifiers introduces new techniques for overcoming the challenges faced by the designer of a Cartesian feedback system. The theory of the new techniques are described and analyzed in detail. The book culminates with the results of the first known fully integrated Cartesian feedback power amplifier system, whose design was enabled by the techniques described. Feedback Linearization of RF Power Amplifiers is a valuable reference work for engineers in the telecommunications industry, industry researchers, academic researchers.

Mobile and Wireless Communications by Salma Ait Fares,Fumiyuki Adachi Pdf

Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. From cell phones to wireless internet to home and office devices, most of the applications are converted from wired into wireless communication. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. A very appealing research area in these environments has been the wireless ad hoc, sensor and mesh networks. These networks rely on ultra low powered processing nodes that sense surrounding environment temperature, pressure, humidity, motion or chemical hazards, etc. Moreover, the radio frequency (RF) transceiver nodes of such networks require the design of transmitter and receiver equipped with high performance building blocks including antennas, power and low noise amplifiers, mixers and voltage controlled oscillators. Nowadays, the researchers are facing several challenges to design such building blocks while complying with ultra low power consumption, small area and high performance constraints. CMOS technology represents an excellent candidate to facilitate the integration of the whole transceiver on a single chip. However, several challenges have to be tackled while designing and using nanoscale CMOS technologies and require innovative idea from researchers and circuits designers. While major researchers and applications have been focusing on RF wireless communication, optical wireless communication based system has started to draw some attention from researchers for a terrestrial system as well as for aerial and satellite terminals. This renewed interested in optical wireless communications is driven by several advantages such as no licensing requirements policy, no RF radiation hazards, and no need to dig up roads besides its large bandwidth and low power consumption. This second part of the book, Mobile and Wireless Communications: Key Technologies and Future Applications, covers the recent development in ad hoc and sensor networks, the implementation of state of the art of wireless transceivers building blocks and recent development on optical wireless communication systems. We hope that this book will be useful for students, researchers and practitioners in their research studies.

Cartesian Feedback Control for MRI Transmitter Array Systems by Marta Gaia Zanchi Pdf

Accurate control of the radio-frequency (RF) electromagnetic fields in Magnetic Resonance Imaging (MRI) is necessary to ensure patient safety and provide high-quality diagnostic capabilities. Precise control is however becoming increasingly difficult to achieve, given the recent trends toward high fields and transmitter array systems. At high fields, imaging is performed in a frequency regime where the wavelength is on the order of, or smaller than, the dimensions of the human body. This leads to prominent wave behavior, non-uniform field patterns, and increased power deposition. Multi-element transmitter array systems with independent phase and amplitude control of their elements support methods that can mitigate these problems. However, in turn, they demand high fidelity RF reproduction and may lead to undesired electromagnetic interactions between elements of the arrays and with interventional devices. Frequency-offset Cartesian feedback can be used to address all of these issues. In combination with the use of polyphase error amplifiers (to implement a low-IF control bandwidth), Cartesian feedback can be used with MRI power amplifiers and transmit coils to increase the fidelity of RF reproduction, without the in-bandwidth DC-offsets and quadrature mismatches that may lead to imaging artifacts such as bright spots and ghosting. In addition, the control system, which includes autotuning circuitry for stability and vector multipliers circuitry for feedback manipulation, can be used to tune the series output impedance of these amplifiers, thereby reducing the likelihood of interactions between elements of transmit array systems. Furthermore, a miniaturized variation of the control system (called Active Cable Trap) can be used on guidewires to suppress undesired currents elicited by coupling with the RF fields of the transmit coils. In an era of rapid progress in high field MRI for clinical applications, the frequency offset Cartesian feedback method and system thus promises to address many of the challenges faced by designers of multi-element transmitter array systems.
