High Frequency Circuit Design And Measurements

An elective course in the final-year BEng progamme in electronic engin eering in the City Polytechnic of Hong Kong was generated in response to the growing need of local industry for graduate engineers capable of designing circuits and performing measurements at high frequencies up to a few gigahertz. This book has grown out from the lecture and tutorial materials written specifically for this course. This course should, in the opinion of the author, best be conducted if students can take a final-year design project in the same area. Examples of projects in areas related to the subject matter of this book which have been completed successfully in the last two years that the course has been run include: low-noise amplifiers, dielectric resonator-loaded oscillators and down converters in the 12 GHz as well as the 1 GHz bands; mixers; varactor-tuned and non-varactor-tuned VCOs; low-noise and power amplifiers; and filters and duplexers in the 1 GHz, 800 MHz and 500 MHz bands. The book is intended for use in a course of forty lecture hours plus twenty tutorial hours and the prerequisite expected of the readers is a general knowledge of analogue electronic circuits and basic field theory. Readers with no prior knowledge in high-frequency circuits are recom mended to read the book in the order that it is arranged. ~ ______ In_t_ro_d_u_c_tl_·o_n ______ ~1 ~ 1.

This ready reference provides electrical engineers with practical information on accurate methods for measuring signals and noise in electronic circuits as well as methods for locating and reducing high frequency noise generated by circuits or external interference. Engineers often find that measuring and mitigating high frequency noise signals in electronic circuits can be problematic when utilizing common measurement methods. Demonstrating the innovative solutions he developed as a Distinguished Member of Technical Staff at AT&T/Bell Laboratories, solutions which earned him numerous U.S. and foreign patents, Douglas Smith has written the most definitive work on this subject. Smith explains design problems related to the new high frequency electronic standards, and then systematically provides laboratory proven methods for making accurate noise measurements, while demonstrating how these results should be interpreted. The technical background needed to conduct these experiments is provided as an aid to the novice, and as a reference for the professional. Smith also discusses theoretical concepts as they relate to practical applications. Many of the techniques Smith details in this book have been previously unpublished, and have been proven to solve problems in hours rather than in the days or weeks of effort it would take conventional techniques to yield results. Comprehensive and informative, this volume provides detailed coverage of such areas as: scope probe impedance, grounding, and effective bandwidth, differential measurement techniques, noise source location and identification, current probe characteristics, operation, and applications, characteristics of sources of interference to measurements and the minimization of their effects, minimizing coupling of external noise into the equipment under test by measurements, estimating the effect of a measurement on equipment operation, using digital scopes for single shot noise measurements, prediction of equipment electromagnetic interference (EMI) emission and susceptibility of performance, null experiments for validating measurement data, the relationship between high frequency noise and final product reliability. With governmental regulations and MIL standards now governing the emission of high frequency electronic noise and the susceptibility to pulsed EMI, the information presented in this guide is extremely pertinent. Electrical engineers will find High Frequency Measurements and Noise in Electronic Circuits an essential desktop reference for information and solutions, and engineering students will rely on it as a virtual source book for deciphering the "mysteries" unique to high frequency electronic circuits.

This book focuses on components such as filters, transformers, amplifiers, mixers, and oscillators. Even the phase lock loop chapter (the last in the book) is oriented toward practical circuit design, in contrast to the more systems orientation of most communication texts.

A classroom-tested book addressing key issues of electrical noise This book examines noise phenomena in linear and nonlinear high-frequency circuits from both qualitative and quantitative perspectives. The authors explore important noise mechanisms using equivalent sources and analytical and numerical methods. Readers learn how to manage electrical noise to improve the sensitivity and resolution of communication, navigation, measurement, and other electronic systems. Noise in High-Frequency Circuits and Oscillators has its origins in a university course taught by the authors. As a result, it is thoroughly classroom-tested and carefully structured to facilitate learning. Readers are given a solid foundation in the basics that allows them to proceed to more advanced and sophisticated themes such as computer-aided noise simulation of high-frequency circuits. Following a discussion of mathematical and system-oriented fundamentals, the book covers: * Noise of linear one- and two-ports * Measurement of noise parameters * Noise of diodes and transistors * Parametric circuits * Noise in nonlinear circuits * Noise in oscillators * Quantization noise Each chapter contains a set of numerical and analytical problems that enable readers to apply their newfound knowledge to real-world problems. Solutions are provided in the appendices. With their many years of classroom experience, the authors have designed a book that is ideal for graduate students in engineering and physics. It also addresses key issues and points to solutions for engineers working in the burgeoning satellite and wireless communications industries.
