Abstract:

The emerging 4.5G/5G cellular network is projected to provide 500 Mb/s of mobile data rate to each user and therefore will require base stations to be equipped with 100-Gb/s backhaul connectivity. Optical fiber networks are widely employed in high-speed wireline communication whereas globally available unlicensed band at 60 GHz is well suited for wireless communication with achievable data rate of 10-20 Gb/s. Therefore, a hybrid fiber-mm-wave communication is being proposed as potentially a cost-effective and flexible solution to the next generation cellular network deployment. A high-speed point-to-point reciprocal wireless optical link is necessary to support this hybrid network in radio backhaul and fiber fronthaul. To address this need, two optical wireless signal transport schemes, RF-over-Fiber (RoF) and Baseband-over-Fiber (BoF), have drawn significant interest and investigation in recent years. However, hybrid fiber-mm-wave networks adopting RoF configuration require the analog bandwidth of O/E (Optical-Electrical) and E/O (Electrical-Optical) interfaces to cover the mm-wave carrier frequency at 60 GHz, which is significantly higher than the targeted data speed of 10-20 Gb/s. The higher operating speed of RoF systems requires prohibitively expensive optical modulators and detectors which are difficult to integrate with the 60-GHz mm-wave circuit even using the most advanced technologies available today. Compared to the RoF scheme, the BoF scheme requires lower bandwidth equivalent to the baseband data rate rather than the carrier frequency. Therefore, it significantly alleviates the bandwidth requirement for O/E and E/O interface and offers advantages of low cost, high speed and integration with advanced CMOS technology. This talk will present a 4-Gb/s fiber-to-mm-wave baseband-over-fiber (BoF) modulator SoC using 65-nm CMOS with a fully integrated 850-nm wavelength optical receiver front-end for short-range backhaul. Design considerations for an improved 10-Gb/s BoF I/Q modulator SoC with integrated mm-wave power amplifier will also be described.

Bio:

Prof. C. Patrick Yue (S’93–M’98–SM’05–F’15) received the B.S. degree from the University of Texas at Austin in 1992 with highest honor and the M.S. and Ph.D. degrees in Electrical Engineering from Stanford University in 1994 and 1998, respectively. He is a Professor in Electronic and Computer Engineering and has served as the Associate Provost for Knowledge Transfer at the Hong Kong University of Science and Technology (HKUST). He is currently on sabbatical leave at Tsinghua University in Beijing, China, as a Chair Professor in the Institute of Microelectronics. He is the Founding Director of the HKUST-Qualcomm Joint Innovation and Research Lab and the Center of Industry Engagement and Internship in the School of Engineering at HKUST. His current research interests include IC design and device modeling for high-speed optical communication, visible light communication, wireless power transfer, and power management for bio-implants. In 1998, Prof. Yue co-founded Atheros Communications (now Qualcomm-Atheros). While working in Silicon Valley, he served as a Consulting Assistant Professor at Stanford. In 2003, he joined Carnegie Mellon University as an Assistant Professor. In 2006, he moved University of California Santa Barbara and was promoted to Professor in 2010. He has contributed to more than 110 peer-reviewed papers, 2 book chapters and holds 14 U.S. patents. He was a co-recipient of the 2003 ISSCC Best Student Paper Award. He has served on the committees of IEEE European Solid-State Circuits Conference, Symposium on VLSI Circuits, International Wireless Symposium, RFIC Symposium, Asian Solid-State Circuits Conference and other IEEE-sponsored conferences. He is an Editor of the IEEE Electron Device Letters and the IEEE Solid-State Circuit Society Magazine. He is an Elected AdCom Member and the Membership Chair of the IEEE Solid-State Circuit Society. Prof. Yue is a member of the Tau Beta Pi Honor Society and an IEEE Fellow.
