Book excerpt: Describing an innovative approach to phased-array control in antenna design This book explores in detail phased-array antennas that use coupled-oscillator arrays, an arrangement featuring a remarkably simple beam steering control system and a major reduction in complexity compared with traditional methods of phased-array control. It brings together in one convenient, self-contained volume the many salient research results obtained over the past ten to fifteen years in laboratories around the world, including the California Institute of Technology's Jet Propulsion Laboratory. The authors examine the underlying theoretical framework of coupled-oscillator systems, clearly explaining the linear and nonlinear formalisms used in the development of coupled-oscillator arrays, while introducing a variety of state-of-the-art methodologies, design solutions, and tools for applying this control scheme. Readers will find: Numerous implementation examples of coupled-oscillator array prototypes A continuum model that permits application of diffusion theory to the analysis of phase dynamics A demonstration of the array behavior through experimental results that validate the linearized theory Examples of how incorporating coupling delay restores causality, including the latest published results Guidance on how to accurately analyze and optimize coupled-oscillator arrays using modern simulation tools A review of current developments, including the design of compact couple-oscillator array antennas Complete with 150 diagrams and photographs, Coupled-Oscillator Based Active-Array Antennas is a highly useful tutorial for antenna designers and a valuable reference for researchers and engineers wishing to learn about this cutting-edge technology.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a tutorial review of van der Pol model, a universal oscillator model for the analysis of modern RC−oscillators in weak and strong nonlinear regimes. A detailed analysis of the injection locking in van der Pol oscillators is also presented. The relation between the van der Pol parameters and several circuit implementations in CMOS nanotechnology is given, showing that this theory is very useful in the optimization of oscillator key parameters, such as: frequency, amplitude and phase relationship. The authors discuss three different examples: active coupling RC−oscillators, capacitive coupling RC−oscillators, and two-integrator oscillator working in the sinusoidal regime. · Provides a detailed tutorial on the van der Pol oscillator model, which can be the basis for the analysis of modern RC−oscillators in weak and strong nonlinear regimes; · Demonstrations the relationship between the van der Pol parameters and several circuit implementations in CMOS nanotechnology, showing that this theory is a powerful tool in the optimization of key oscillator parameters; · Provides three circuit prototypes implemented in modern CMOS nanotechnology in the GHz range, with applications in low area, low power, low cost, wireless sensor network (WSN) applications (e.g. IoT, BLE).

Available in PDF, EPUB and Kindle. Book excerpt: Necessary conditions are established for the voltage transfer matrix of a transformerless grounded network composed of ideal resistors, inductors, capacitors (RLC), and grounded unity gain amplifiers. These conditions are also shown to be sufficient for realization as the voltage transfer matrix of a transformerless grounded network containing RC and not more than one grounded unity gain amplifier per matrix row. Similar necessary, and sufficient, conditions are presented for transformerless grounded input, nongrounded output networks composed of these same passive and active elements. The grounded input, nongrounded output case requires not more than two grounded unity gain amplifiers per matrix row for its synthesis. In the two-port nongrounded case a special procedure makes it possible to realize the transfer function by the proper connection of two identical threeterminal networks. (Author).

All the essential topics in oscillator design anddevelopment are covered, including: * Device and resonator technology * Study of noise sources * Analysis methods * Design, calculation, and optimization methodologies * Practical design of single and coupled oscillators While most of the current literature in the field concentrates onclassic design strategies based on measurements, simulation, andoptimization of output power and phase noise, this text offers aunique approach that focuses on the complete understanding of thedesign process. The material demonstrates important design rulesstarting with the selection of best oscillator topology, choice oftransistors, and complete phase noise analysis that leads tooptimum performance of all relevant oscillator features. Alsoincluded are CMOS oscillators, which recently have become importantin cellular applications. For readers interested in specializedapplications and topics, a full chapter provides all the necessaryreferences.
