This book describes a new design methodology that allows optimization-based synthesis of RF systems in a hierarchical multilevel approach, in which the system is designed in a bottom-up fashion, from the device level up to the (sub)system level. At each level of the design hierarchy, the authors discuss methods that increase the design robustness and increase the accuracy and efficiency of the simulations. The methodology described enables circuit sizing and layout in a complete and automated integrated manner, achieving optimized designs in significantly less time than with traditional approaches.

Fábio Passos received the Ph.D. degree from the Universidad de Sevilla, Seville, Spain, in 2018, while conducting his work in the Instituto de Microelectrónica de Sevilla (IMSE-CNM), Seville, Spain. He has performed research stays is several academic and industrial institutions such as IMEC, Instituto de Telecomunicações, University of Barcelona, and Analog Devices. He is currently a Researcher with the Instituto de Telecomunicações, Lisbon, Portugal. His research interests include the modeling of RF passive devices and automated design methodologies for RF and mm-wave circuits. He was a recipient of several Best Paper Awards, the EDA Competition Award in SMACD 2016, and the Prestigious EDAA Outstanding Dissertation Award, in 2019. Elisenda Roca received the Ph.D. degree in physics from the University of Barcelona, Spain, in 1995. From November 1990 to April 1995, she worked at IMEC, Leuven, Belgium. Since 1995, she has been with the Instituto de Microelectrónica de Sevilla, (IMSE-CNM-CSIC), Spain, where she holds the position of Tenured Scientist. She has also coauthored more than 150 articles in international journals, books, and conference proceedings.
