Integrated Inductors and Transformers: Characterization, Design and Modeling for RF and MM-Wave Applications / Edition 1

by Egidio Ragonese, Giuseppe Palmisano, Angelo Scuderi, Tonio Biondi

Overview

With the ability to improve performance, reduce fabrication costs, and increase integration levels of both RX and TX sections of the RF/mm-wave front-end, passive inductive components have experienced extraordinary growth in ICs. Therefore, a fundamental understanding of monolithic inductors and transformers has become essential for all process engineers and circuit designers.

Supplying balanced coverage of the technology and applications, Integrated Inductors and Transformers: Characterization, Design and Modeling for RF and mm-Wave Applications provides a complete overview of the design, fabrication, and modeling of monolithic inductors and transformers. It considers the underlying physics and theoretical background of inductive components fabricated on a semiconductor substrate.

• Deals with both inductors and transformers and their application in RF/mm-wave ICs
• Focuses on silicon-based inductive components and their performance optimization in RF/mm-wave ICs
• Provides insight into lumped scalable modeling of both inductors and transformers
• Covers concepts of system calibration, test pattern parasitics, and de-embedding for on-wafer measurements of passive devices
• Illustrates practical applications of theoretical concepts by means of meaningful circuit design examples

Highlighting the pressing requirements of the wireless market and evolving communication standards, the text provides a comprehensive review of recently developed modeling techniques and applications. It also includes helpful rule-of-thumb design guidelines and commonly employed optimization strategies to help kick-start your design, fabrication, and modeling efforts.
