This book describes innovative techniques and the theoretical background for design and analysis of high performance RF/Microwave transmitters. It introduces new, robust linearization/efficiency enhancement techniques, applicable to all of the switched mode power amplifiers. Novel analysis methods associated with these new techniques are also introduced and supporting measurement results are documented. Innovative graphical representation methods are used to help the reader understand the matter intuitively. Applications for the techniques discussed are very extensive, ranging from data convertors to RF/Microwave/mm-wave wireless/wire line transmitters. The authors have avoided using lengthy formulas in the discussion and have used an intuitive and simple approach to go through the necessary details. Readers will gain valuable understanding of the dither phenomenon, its mechanism, effect and undesired side effects. The novel architectures introduced are simple, don’t require complicated DSP techniques and are easy to implement.

Noise-Driven Phenomena in Hysteretic Systems by Mihai Dimian,Petru Andrei Pdf

Noise-Driven Phenomena in Hysteretic Systems provides a general approach to nonlinear systems with hysteresis driven by noisy inputs, which leads to a unitary framework for the analysis of various stochastic aspects of hysteresis. This book includes integral, differential and algebraic models that are used to describe scalar and vector hysteretic nonlinearities originating from various areas of science and engineering. The universality of the authors approach is also reflected by the diversity of the models used to portray the input noise, from the classical Gaussian white noise to its impulsive forms, often encountered in economics and biological systems, and pink noise, ubiquitous in multi-stable electronic systems. The book is accompanied by HysterSoft© - a robust simulation environment designed to perform complex hysteresis modeling – that can be used by the reader to reproduce many of the results presented in the book as well as to research both disruptive and constructive effects of noise in hysteretic systems.

Advances in Analog and RF IC Design for Wireless Communication Systems by Salvatore Levantino,Carlo Samori Pdf

In less than one decade after their introduction into radio-frequency applications, digital fractional-N phase-locked loops (PLLs) have become a relevant topic in microelectronic research and a practical solution for products. In addition to the well-known advantages, such as their silicon area occupation scaling as technology node and their easier portability to new nodes, digital PLLs enable easy and low-cost implementation of calibration techniques, which substantially reduce spurious tones and remove other major analog impairments. In wideband PLLs, the ultimate level of spur performance is often bounded by the time resolution and the linearity of the time-to-digital converter within the digital PLL. Methods for mitigating its nonlinearity such as those based on element randomization and large-scale dithering are discussed. The use of fractional-N dividers based on digital-to-time converters, as a means to relax the design of the time-to-digital converter, is also reviewed. This concept is extended to the limit case of a single-bit time-to-digital converter, which provides best PLL noise–power trade-off with good spur performance.
