Abstract:

The development of integrated circuit manufacturing processes in the last few years has translated into ever smaller features for the elements they are comprised of, being now just 5 nm.  This enables the attainment of higher frequencies of operation, in the range of tens to hundreds of GHz.  Since modern processes are based on silicon, and circuits are designed mostly using CMOS technology, circuits can be designed and manufactured to operate with very low power, making them ideal for high-frequency, wireless communications with hand-held devices.  But besides having transistors, integrated circuits include passive devices such as inductors, capacitors, resistors, and interconnects, among others. Before sending a circuit to the fab, the designer has to be sure that it is going to work as desired, and thus its behavior has to be extensively simulated using computers.  In order to achieve trustworthy simulations, however, it is fundamental to have models —physical, mathematical, electrical— for each device and component, models which are obtained from individual characterization processes. This talk focuses on presenting some of the basic concepts of device characterization and modeling techniques for high-frequency applications, highlighting the second-order effects present in this frequency range, and suggesting a methodology to use to obtain trustworthy models for simulation routines.

Dr. Roberto Murphy is a Full Researcher “C” at INAOE, where he has worked since 1988, associated with the Electronics Coordination. His field of interest focuses on high-frequency electronics, particularly on the physics, modeling, and characterization of devices for wireless communication applications.

In recent years, he has dedicated his work to the study, design, measurement, and modeling of antennas. Additionally, he has carried out administrative duties at INAOE for more than 18 years; he served as Director of Academic Training, Director of Research, and Head of the Electronics Department. He also served as Treasurer, Vice President, and President of the Mexican Council for Graduate Studies (COMEPO), and as a member of the Board of Directors and later President of the Iberoamerican Science and Technology Education Consortium (ISTEC), a non-profit academic organization based in Albuquerque, New Mexico, USA.

He has published more than 160 works in scientific journals, conferences, and proceedings, has taught over 100 postgraduate courses, and has supervised 38 graduate theses.

He is a Level 2 member of the National System of Researchers, a member of the Mexican Academy of Sciences, of the European Microwave Association, and a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), where he also serves as a Distinguished Lecturer for the Electron Devices Society (EDS).
