Once every week while school is in session, EECS invites a distinguished researcher or practitioner in a computer science or electrical and computer engineering-related field to present their ideas and/or work. Talks are generally targeted to electrical engineering and computer science graduate students. This colloquium series is free and open to everyone.

Upcoming Colloquia

Frequency multipliers for crystal oscillators

Wednesday, July 25, 2018 - 10:30am to 11:30am

Low-noise high-frequency reference clocks are needed in all high-performance clock multipliers. Such reference clocks are typically provided by crystal oscillators (XOs). While higher frequency reference clocks greatly help in improving the noise performance of clock multipliers, XO output frequencies are typically limited to few 10s of MHz. To alleviate this limitation, I’ll present techniques to double and quadruple the XO output frequency with minimal noise and power penalty. I’ll describe calibration schemes that can overcome circuit imperfections and improve immunity to process, voltage, and temperature variations. To validate the presented ideas, I will show experimental results obtained from two prototype integrated circuits.

Speaker Bio

Pavan Hanumolu is currently a Professor in the Department of Electrical and Computer Engineering at the University of Illinois, Urbana-Champaign. He received Ph.D. degree from the School of Electrical Engineering and Computer Science at Oregon State University, in 2006, where he subsequently served as a faculty member till 2013. Dr. Hanumolu’s research interests are in energy-efficient integrated circuit implementation of analog and digital signal processing, sensor interfaces, wireline communication systems, and power conversion.

Learning to Learn: Overview of My Research Work at OSU and beyond

Friday, August 10, 2018 - 10:00am to 11:00am
KEC 1001

Speaker Information

Hashem Nehrir
Electrical and Computer Engineering Department
Montana State University-Bozeman


This informal presentation will give a quick overview of Dr. Nehrir’s research work starting from what he did at Oregon State on real-time computer control of electric machines and on Synchronous Machine Modeling for inclusion in power system stability programs to diverse research projects in over three decades at Montana State on residential load modeling and control for distribution system peak load shaving, alternative energy power generation system modeling and control, microgrid power management, and on smart grid resiliency. He will focus on the value of his education at Oregon State, where he “learned how to learn.”

Speaker Bio

Dr. Nehrir received his BS, MS, and Ph.D. degrees all in electrical engineering from Oregon State University in 1969, 1971 and 1978, respectively. He has been a member of the Electrical & Computer Engineering faculty at Montana State University (MSU) since 1987, where he received the MSU's Wiley Faculty Award for Meritorious Research in 2010.

He is the 2016 recipient of the IEEE Power & Energy Society’s Ramakumar Family Renewable Energy Excellence Award and a Life Fellow of IEEE for contribution to alternative energy power generation system modeling and control.
