From High Speed to Radiofrequency Applications
Publication Date: May 2014 Hardback 176 pp.
Presenting the concepts necessary for the design and testing of radiofrequency and high-speed circuits, this book explores signal and propagation theory for various circuit levels, from the chip to the PCB. The co-existence of high-speed wideband signals, radiofrequency signals and supply circuits is developed in order to provide design rules for engineers and Masters-level students – it can also serve as basic training for technicians or engineers wishing to approach the design of high-speed circuits, or mixed digital and radiofrequency systems.
The first chapter is dedicated to the reduction of the rise time of digital signals linked to transmission in a limited-bandwidth channel and the effect on the parameters of the digital signal. Chapter 2 addresses the modeling basics of interconnects for high-speed applications. The third chapter introduces controlled impedance, mismatching, and the various reflections associated with them when signal frequencies increase. Chapter 4 discusses the concept of transmission lines, which are necessary for handling controlled-impedance interconnects. Chapter 5 introduces the concept of S parameters, used to determine circuit and system performances in the frequency domain. Chapter 6 addresses techniques of time-domain measurement via time-domain reflectometry (TDR). Finally, Chapter 7 introduces the phenomenon of coupling as the source of interference and crosstalk in packages and data buses.
