High-Speed Devices and Circuits with THz Applications

Preface

This book was motivated by the desire to explore the future perspectives of high-frequency technologies by presenting the state-of-the-art results in both new device developments and circuit implementations. It discusses issues for the circuit operation beyond 100 GHz with respect to device physics, circuit implementations, and some technological bottlenecks for system implementations. Also, recent device and circuit results using SiGe technologies as an alternative to Si complementary metal-oxide-semiconductor (CMOS) devices are presented.

Evolutionary device developments let people consider widening the frequency spectrum of interest up to terahertz. For example, as Si CMOS technologies evolve from 65 nm to 40 nm to 28 nm and further, ...
