Available in PDF, EPUB and Kindle. Book excerpt: This book describes up-to-date technology applied to high-K materials for More Than Moore applications, i.e. microsystems applied to microelectronics core technologies. After detailing the basic thermodynamic theory applied to high-K dielectrics thin films including extrinsic effects, this book emphasizes the specificity of thin films. Deposition and patterning technologies are then presented. A whole chapter is dedicated to the major role played in the field by X-Ray Diffraction characterization, and other characterization techniques are also described such as Radio frequency characterization. An in-depth study of the influence of leakage currents is performed together with reliability discussion. Three applicative chapters cover integrated capacitors, variables capacitors and ferroelectric memories. The final chapter deals with a reasonably new research field, multiferroic thin films.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced concepts for wireless technologies present a vision of technology that is embedded in our surroundings and practically invisible. From established radio techniques like GSM, 802.11 or Bluetooth to more emerging technologies, such as Ultra Wide Band and smart dust motes, a common denominator for future progress is the underlying integrated circuit technology. Wireless Technologies responds to the explosive growth of standard cellular radios and radically different wireless applications by presenting new architectural and circuit solutions engineers can use to solve modern design problems. This reference addresses state-of-the art CMOS design in the context of emerging wireless applications, including 3G/4G cellular telephony, wireless sensor networks, and wireless medical application. Written by top international experts specializing in both the IC industry and academia, this carefully edited work uncovers new design opportunities in body area networks, medical implants, satellite communications, automobile radar detection, and wearable electronics. The book is divided into three sections: wireless system perspectives, chip architecture and implementation issues, and devices and technologies used to fabricate wireless integrated circuits. Contributors address key issues in the development of future silicon-based systems, such as scale of integration, ultra-low power dissipation, and the integration of heterogeneous circuit design style and processes onto one substrate. Wireless sensor network systems are now being applied in critical applications in commerce, healthcare, and security. This reference, which contains 25 practical and scientifically rigorous articles, provides the knowledge communications engineers need to design innovative methodologies at the circuit and system level.

This book was released on 2022-06-01 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tunable Materials with Applications in Antennas and Microwaves is a stimulating topic in these modern times. With the explosion of the new generation of the wireless world, greater emphasis than ever before is being placed on the analysis and applications of modern materials. This book describes the characteristics of Ferrites and Ferroelectrics and introduces the reader to Multiferroics. Represents, in a simple manner, the solid state physics and explains the permittivity and permeability tensor characteristics for the tunable materials of infinite and finite dimensions. Gives the applications of tunable materials in resonators, filters, microstrips, striplines, antennas, phase shifters, capacitors, varactors, and frequency selective surfaces. Describes in detail the mathematical analysis for spin and magnetostatic waves for infinite medium, thin slab films, and finite circular discs. The analysis contains original work, which the reader may extend in the future. Provides multiferroics, which are ferrite and ferroelectric composites. Multiferroics are very promising tunable materials which are believed will offer many applications in the near future. Contains the planar transmission lines with analytic formulas for multilayer microstrips, transmission lines, and waveguides with isotropic as well as anisotropic dielectric and magnetic materials. Also, gives the formulas to analyze the layered category of transmission lines with multiferroics. This book is intended for antenna and microwave engineers as well as for graduate students of Materials Science and Engineering, Electrical & Computer Engineering, and Physics Departments.

Download or read book Phase Noise in Signal Sources written by W. P. Robins and published by IET. This book was released on 1984 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a thorough treatment of phase noise, its relationship to thermal noise and associated subjects such as frequency stability. The design of low phase noise signal sources, including oscillators and synthesisers, is explained and in many cases the measured phase noise characteristics are compared with the theoretical predictions. Full theoretical treatments are combined with physical explanations, helpful comments, examples of manufactured equipment and practical tips. Overall system performance degradations due to unwanted phase noise are fully analysed for radar systems and for both analogue and digital communications systems. Specifications for the acceptable phase noise performance of signal sources to be used in such systems are derived after allowing for both technical and economic optimisation. The mature engineer whose mathematics may be somewhat rusty will find that every effort has been made to use the lowest level of mathematical sophistication that is compatible with a full analysis and every line of each mathematical argument has been set out so that the book may be read and understood even in an armchair. Due to a novel approach to the analytical treatment of narrow band noise, the book is simple to understand while simultaneously carrying the analysis further in several areas than any existing publication.

Download or read book Design of Frequency Agile Circuits Using Barium Strontium Titanate Varactor written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-standard and multi-band radio are the next milestone in the ever developing radio industry. Frequency agile circuits are an enabling technology which allows us to achieve this goal. It is a low cost and efficient technology that provides the necessary flexibility required to implement multi-standard and multi-band radios. One important circuit component which comes easily to one's mind for frequency tunability is a varactor; with so many constraints of high tuning range, fast tuning speed and low loss on varactor, new technologies have come up to full fill these requirements. Among various varactor technologies, Barium Strontium Titanate (BST) has shown promise in the implementation of various tunable circuits like filters, voltage controlled oscillators (VCO), and tunable matching networks with good performance. This thesis concentrates on the use of BST for implementation of frequency agile circuits. Two circuits which form an integral part of any RF transreciever are a VCO and a low noise amplifier(LNA). These circuits were chosen to demonstrate the usability of BST varactor as a tunable element. The VCO implementation shows how a BST varactor can be integrated with modern integrated circuit process like IBM 0.18 um SiGe BiCMOS process. A low power VCO with 14% tuning at flow = 11.27 GHz and a phase noise of -104.5dBc @ 1MHz offset has been designed and fabricated. Special interface technique like Flip Chip has been used to interface the BST varactor to the SiGe VCO core circuit. The second circuit implementation is a tunable matching network for a low noise amplifier. The tuning range achieved was 140 MHz(885MHz-1.025GHz) (14.65%) for deltaV bias= 80V. The input return loss was better than 14.5dB throughout the tuning range and the output return loss was better than 13dB for the same. The gain remained almost constant over the tuning range with a change of 1dB nominally being 19.4dB. The IIP3 was better than -3.55 dB over the tuning range with little varia.
