Negative Group Delay Devices: From Concepts to Applications introduces the theoretical concept, analysis, design methodology and implementation of negative group delay (NGD). The NGD concept is a recent topic in electrical and electronic engineering research based on an unconventional function; the generation of an output signal seemingly in time-advance of the input signal. The NGD function has been exploited to develop experimental high-performance electronic devices, and novel design features of radio frequency (RF) and microwave electronic devices, such as filters, power dividers and amplifiers.
The aim of the book is to advance understanding of the NGD principle and its applications. Recent results and outcomes for the different methodologies used to elaborate the NGD function are shared in each chapter, and approaches relevant to various devices are described.
Blaise Ravelo is an Associate Professor in electronics and multiphysics engineering, and a pioneer of the development of negative group delay (NGD) circuits. He is regularly involved, initiated and led national and international R&D&I projects funded by the programs FP7, INTERREG, ANR, FUI, Horizon 2020, Euripides on electronic, microwave, and EMC engineering. He is co-author of more than 220 papers published in international journals, book chapters, and conferences.
This book will be of particular interest to researchers, academics and postdoctoral students interested in signal processing in electronic, radio frequency, microwave and optoelectronic devices, and particularly those investigating unconventional circuit and system design.
