Book Description
A nonlinear relation between current and voltage for schottky resonant tunneling diode is used. A general form of equation similar to VanDer Pol equation is obtained. A Resonant tunneling diode(RTD) has a negative differential resistance that means when the voltage increases the current decreases. This property is very useful for oscillators manufacture. Nonlinear transmission lines is considered to show that it canbe used in oscillators and to show that it can reshape the sinusoidal signals to othershapes by using OrCad and mathematica programming.

Book Description
This book presents and discusses alternatives to ordinary transmission lines for the design and implementation of advanced RF/microwave components in planar technology. This book is devoted to the analysis, study and applications of artificial transmission lines mostly implemented by means of a host line conveniently modified (e.g., with modulation of transverse dimensions, with etched patterns in the metallic layers, etc.) or with reactive loading, in order to achieve novel device functionalities, superior performance, and/or reduced size. The author begins with an introductory chapter dedicated to the fundamentals of planar transmission lines. Chapter 2 is focused on artificial transmission lines based on periodic structures (including non-uniform transmission lines and reactively-loaded lines), and provides a comprehensive analysis of the coupled mode theory. Chapters 3 and 4 are dedicated to artificial transmission lines inspired by metamaterials, or based on metamaterial concepts. These chapters include the main practical implementations of such lines and their circuit models, and a wide overview of their RF/microwave applications (including passive and active circuits and antennas). Chapter 5 focuses on reconfigurable devices based on tunable artificial lines, and on non-linear transmission lines. The chapter also introduces several materials and components to achieve tuning, including diode varactors, RF-MEMS, ferroelectrics, and liquid crystals. Finally, Chapter 6 covers other advanced transmission lines and wave guiding structures, such as electroinductive-/magnetoinductive-wave lines, common-mode suppressed balanced lines, lattice-network artificial lines, and substrate integrated waveguides. Artificial Transmission Lines for RF and Microwave Applications provides an in-depth analysis and discussion of artificial transmission lines, including design guidelines that can be useful to researchers, engineers and students.

Book Description
Nonlinear transmission lines are monolithic microwave integrated circuits for economically generating ultrafast voltage waveforms with varactor diodes. With applications in high speed sampling and sensing, these circuits are used to convert readily available microwave power into the low-terahertz through the generation of voltage shockwaves. Existing diode designs have focused on cut-off frequency and capacitance modulation without addressing current saturation, a critical limiter of slew rate (voltage/falltime). In this thesis, we introduce optimized high voltage ultrafast double-uniform Schottky diode structures that significantly increase the theoretical slew rate and breakdown voltage. We designed, simulated, and fabricated diode structures and circuits on gallium arsenide, measuring record slew rates. This work highlights a critical design parameter for frequency generating diodes, providing the ground work for large power increases in ultrafast diode-based circuits.

Book Description
The packaging of electronic devices and systems represents a significant challenge for product designers and managers. Performance, efficiency, cost considerations, dealing with the newer IC packaging technologies, and EMI/RFI issues all come into play. Thermal considerations at both the device and the systems level are also necessary. The Electronic Packaging Handbook, a new volume in the Electrical Engineering Handbook Series, provides essential factual information on the design, manufacturing, and testing of electronic devices and systems. Co-published with the IEEE, this is an ideal resource for engineers and technicians involved in any aspect of design, production, testing or packaging of electronic products, regardless of whether they are commercial or industrial in nature. Topics addressed include design automation, new IC packaging technologies, materials, testing, and safety. Electronics packaging continues to include expanding and evolving topics and technologies, as the demand for smaller, faster, and lighter products continues without signs of abatement. These demands mean that individuals in each of the specialty areas involved in electronics packaging-such as electronic, mechanical, and thermal designers, and manufacturing and test engineers-are all interdependent on each others knowledge. The Electronic Packaging Handbook elucidates these specialty areas and helps individuals broaden their knowledge base in this ever-growing field.

Book Description
The growth in RF and wireless/mobile computing devices that operate at microwave frequencies has resulted in explosive demand for integrated circuits capable of operating at such frequencies in order to accomplish functions like frequency division, phase shifting, attenuation, and isolators and circulators for antennas. This book is an introduction to such ICs, combining theory and practical applications of those devices. In addition to this combined theory and application approach, the author discusses the critical importance of differing fabrication materials on the performance of ICs at different frequencies. This is an area often overlooked when choosing ICs for RF and microwave applications, yet it can be a crucial factor in how an IC performs in a given application. Gives reader a solid background in an increasingly important area of circuit design Emphasis on combination of theoretical discussions with practical application examples In-depth discussion of critical, but often overlooked topic of different fabrication material performances at varying frequencies

Book Description
This volume covers the topic of advanced plasma processing techniques, from the fundamental physics of plasmas to diagnostics, modeling and applications such as etching and deposition for microelectronics. The use of plasmas for patterning on a submicron scale has enabled successive generations of continually smaller transistors, lasers, micromachines, sensors and magnetic read/write heads that have formed the basis of our information age. This volume is the first to give coverage to this broad area of topics in a detailed fashion, especially in the rapidly expanding fields of micro-mechanical machines, photomask fabrication, magnetic data storage and reactor modeling. It provides the reader with a broad array of topics, authored by the leading experts in the field.
