Integrated Systems Seminar Series - Spring 2014

Speaker: Waleed Khalil, Ohio State University

Talk Title: Towards the Design of Robust Wide Tuning Range and Low Phase Noise mm-Wave VCOs: Challenges, Solutions and Recent Advances

Series: Integrated Systems Seminar Series

Abstract: Over the past few years, there has a been a growing demand for mm-wave circuits with emerging applications such as Gigabit WLAN and Short Range Radars. More recently, mm-wave technology has been touted for future 5G cellular systems, eclipsing a long era where low GHz systems dominated the field of wireless systems. Moving forward, we expect the mass market adaptation of these technologies to force the shift towards low-cost Si-based processes. However, in to order to succeed in this space, we need to push the Si performance closer to the well-entrenched incumbent III-V technologies. In the VCO domain, major challenges still remain in meeting the tuning range and phase noise specifications while maintaining high yield. In light of these challenges, this seminar will present our current and future research work to build mm-wave VCOs circuits with record benchmarks. Different topologies in both CMOS and SiGe technologies will be covered. Also, a new analytical model that facilitates an efficient optimization of the VCO turning range and phase noise is presented. The model is exploited to analyze the impact of technology scaling on the achievable performance bounds.

Biography: Dr. Khalil received his B.S.E.E. and M.S.E.E degrees from the University of Minnesota in 1992 and 1993, respectively. In 2008, he received his PhD degree in Electrical Engineering from Arizona State University. He is currently serving as an Assistant Professor at the ECE department and the ElectroScience Lab, The Ohio State University. He conducts research in SDRs, digital intensive RF and mm-wave circuits and systems, high performance clocking circuits and GHz A/D and D/A circuits. Prior to joining OSU, Prof. Khalil spent 16 years at Intel Corporation where he held various technical and leadership positions in wireless and wireline communication groups. While at Intel, he was appointed the lead engineer at the advanced wireless communications group, where he played an instrumental role in the development of the industry’s first Analog Front-end IC for third generation radios (3G). He later co-founded a startup group to develop Intel’s first RF front-end IC, as a principle leader of the radio transmitter chain. During his work at Intel, he received the prestigious Intel Quality Award in 2005. Dr. Khalil’s research group has received several paper awards, among them TSMC’s outstanding research award in 2010 and the best paper award in the Wireless Innovation Forum and Phase Array Symposium in 2013. He authored 10 issued and several other pending patents, over 50 journal and conference papers and three books/book chapters. He is a senior member of IEEE and serves in the steering committee for the RFIC Symposium and as a guest faculty at the Air Force Research Laboratory.
