ED/PHO/GEDC Seminar: Mixed-Domain Nano-Systems for Integrated Radio Frequency Communication Applications
Sep. 18, 2019 | 11 am - 12:30 pm | Technology Square Research Building, 1st Floor Auditorium
 

Abstract: The Smart Connected World paradigm is based upon communication hardware that meet stringent requirements on performance, size, weight, and power consumption (SWaP). For example, the new wireless protocols (i.e. 5G and beyond) enforce extreme enhancement of spectrum use efficiency, bandwidth, and reconfigurability, which requires substantial transformation of available RF front-end modules. In this talk, I will discuss mixed-domain RF nano-systems that are realized at the intersection of semiconductor electronics, nano-acoustics, and atomic-layered ferroelectrics. These systems are poised to enable unprecedented functionalities, in ultra-miniaturized SWaP, for emerging communication applications. In the first part, I will discuss the design and fabrication innovations that pave the way for monolithic integration of nano-mechanical spectral processors on semiconductor platforms. Specifically, I will introduce the fin-based high-Q M/NEMS resonator technology and atomic-layered ferroelectric-hafnia transducers as the two enablers for realization of the first integrated cm- and mm-wave spectral processors. In the second part, I will present novel semiconductor-based RF components that exploit linear and nonlinear interactions of acoustic waves and electric fields to realize previously unavailable processing capabilities at the chip scale. In this context, I will go over the design and implementation of acousto-electric amplifiers, non-reciprocal filters, frequency reference chains, and instinctually adaptive limiters, and discuss their application space.

Bio: Roozbeh Tabrizian received his B.S. in Electrical Engineering from Sharif University of Technology, Tehran, Iran, in 2007, and Ph.D. in Electrical and Computer Engineering from Georgia Institute of Technology, 2013. In 2014, he joined the Department of Electrical Engineering, University of Michigan as a Postdoctoral research fellow. In August 2015, he joined the Department of Electrical and Computer Engineering, University of Florida as an Assistant Professor.

His research at the University of Florida involves linear, nonlinear, and nonreciprocal nano-acoustic devices, RF M/NEMS, mixed-domain nanosystems for time-keeping / transfer, frequency reference, and spectroscopy applications, and micro- / nano-fabrication technologies. Dr. Tabrizian is the recipient of DARPA Young Faculty Award (2019) and NSF CAREER award (2018). His research has resulted in more than 50 journal and conference papers, 2 book chapters, 3 published patents and 10 patent applications. He and his students are the recipients of outstanding paper awards at the IEEE International Conference on Micro Electro Mechanical Systems (MEMS) and International Conference on Solid-State Sensors, Actuators, and Microsystems (Transducers).
