Dr. Joel Harley University of Utah Electrical & Computer Engineering Department When: Monday, September 15, 2014 at 3:05 p.m.Where: Warnock 1250 Abstract In engineering and the sciences, there is considerable interest in new technology to sense and monitor large, physical environments. These systems have applications in many fields, including civil and aerospace engineering, medicine, oceanography, and seismology. For civil and aerospace applications, these technologies can be used to noninvasively monitor the structural integrity of bridges, pipes, airplanes, and other modern structures to reduce maintenance costs and prevent catastrophic failures in transportation, power, and resource distribution networks. Ultrasonic guided waves (waves that are “guided” by the geometry of the environment) have been of particular interest for monitoring critical infra-structures due to their sensitivity to damage and capability to interrogate large areas at once. To detect, locate, and evaluate damage, ultrasonic guided waves are measured and analyzed using various signal processing strategies. However, successfully detecting and locating damage is challenging because complex propagation environments significantly distort the waves as they travel through the medium. This talk presents a signal processing framework for overcoming these challenges by combining the physical principles of ultrasonic waves with novel data-driven signal processing strategies. Through experimental data, I demonstrate how to characterize complex environments and use their properties to improve to improve detection, localization, and characterization performance. We briefly discuss how these strategies can be extended to other applications. Speaker Biography Joel B.

Dr. Jeffrey S. Walling University of Utah Electrical & Computer Engineering Department When: Monday, September 22, 2014 at 3:05 p.m.Where: Warnock 1250 Abstract CMOS is used nearly ubiquitously for digital computation, and as such plays an ever increasing role in our lives as we increasingly use computation to improve working efficiency. Increasing levels of integration have made it possible to embed analog and RF circuits with digital processing on a single integrated circuit. The RF power amplifier (PA) has been the exception to integration in CMOS, owing to its relatively poor performance (e.g., peak output power and energy efficiency) when compared to other semiconductor technologies (e.g., III-V compounds and SiGe). In this talk I will introduce digital PAs (DPAs), which leverage CMOS inherent strengths of fast switching speeds and superior lithographic matching to yield a linear, efficient digital power amplifier. I will also examine current research in the University of Utah Power Efficient RFIC lab addressing limitations in DPAs, and high power PAs using GaN devices. The aim of such PAs is to enable reconfigurable operation for software-defined and cognitive radios networks.

Univ. of Utah ECE Dept. Frontiers in Engineering Innovation Judd Distinguished Lecture Dr. T.E. Schlesinger Benjamin T. Rome Dean Whiting School of Engineering Johns Hopkins University When: Monday, October 20, 2014 at 3:05 p.m.Where: Sorenson Molecular Biotechnology Building (SMBB) 2650 - Auditorium Abstract The latter half of the twentieth century has been the age of the transistor. To a great extent the fabric of technology that has transformed science, engineering and society through computation, communication, information storage, sensing and networking is based on the transistor and the integration of this device in the billions. As one looks to the future it seems unlikely that the next revolution in technology will emerge in this space. Rather it appears more likely that it is the use of engineering technologies to advance understanding in biology, medicine, and healthcare and to transform these with the discipline of engineering that will produce the type of “game changing” advances that will once again create transformative changes in societies. The organizations that understand how to thrive in this new reality in terms of education, research and the translation of these to impact society will lead this change. In this presentation I will offer a view of why the focus of technology will shift in the coming years and how even at the level of undergraduate curricula institutions must respond to these and other changes so as to position themselves for this new reality. Speaker Biography T.E. Schlesinger is the Benjamin T. Rome Dean of the Whiting School of Engineering at Johns Hopkins University.

Dr. Shiuh-hua Wood Chiang Brigham Young University Electrical & Computer Engineering Department When: Monday, November 10, 2014 at 3:05 p.m.Where: Warnock 1250 Abstract Analog-to-digital converters (ADCs) are widely used in communication systems to interface analog and digital circuits. While the speed, power, and area of digital circuits directly benefit from the decreasing channel length of CMOS devices, analog circuits suffer from reduced headroom, lower intrinsic gain, and higher device mismatch. Consequently, it has been increasingly difficult to design high-speed and low-power pipelined ADCs using conventional op amps. This work presents a pipelined ADC that employs novel “charge-steering” op amps to relax the trade-offs among speed, noise, and power consumption. Such op amps afford a fourfold increase in speed and a twofold reduction in noise for a given power consumption and voltage gain. Using a new clock gating technique, the ADC digitally calibrates the nonlinearity and gain error at full speed. A prototype realized in 65-nm CMOS technology achieves a resolution of 10 bits with a sampling rate of 800 MHz, a power consumption of 19 mW, an SNDR of 52.2 dB at Nyquist, and an FoM of 53 fJ/conversion-step. A new background calibration technique is also proposed to accommodate temperature and supply variations. Current research efforts include extending the digital calibration techniques to ultra low-power neural amplifiers. Speaker Biography Shiuh-hua Wood Chiang received his B.S. degree in Computer Engineering from the University of Waterloo, Waterloo, Canada in 2007, the M.S. degree in Electrical Engineering from the University of California, Irvine in 2009, and the Ph.D. degree in Electrical Engineering from the University of California, Los Angeles in 2013.

Dr. Ajay Nahata University of Utah Electrical & Computer Engineering Department When: Monday, November 17, 2014 at 3:05 p.m.Where: Warnock 1250 Abstract In recent years, there has been great interest in the field of plasmonics. Much of the focus has been on studying the phenomena at optical frequencies, because of the potential for a wide variety of nanophotonic device applications. Although there has been excellent progress in this area, any resulting plasmonic device technologies would need to compete with existing optical capabilities. This is not the case in the THz spectral range. Although significant advances has been made in creating THz sources and detectors, there is a nearly complete lack of other device capabilities in the THz spectral range, which severely limits the development of useful technologies in areas such as communications, computing and imaging. A significant issue is that conventional dielectric materials are highly lossy at these frequencies. In this talk, I will discuss why plasmonics is extremely well suited for THz applications and demonstrate that the breadth of materials appropriate for plasmonics is dramatically larger than at optical frequencies. Speaker Biography Dr. Ajay Nahata received his Bachelor’s degree from MIT and his Master’s and Ph.D. degrees from Columbia University, all in electrical engineering. He worked in industry for a total of nearly nine years, first at AlliedSignal Inc. (now Honeywell International) and later with NEC Research Institute. Since August 2003, he has been with the Department of Electrical and Computer Engineering at the University of Utah. His current research programs are in the areas of THz optoelectronics and nanophotonics. His research interests include ultrafast optics, nonlinear optics, nanophotonics, and, more generally, studying interesting optical phenomena and exploring potential applications.

Univ. of Utah ECE Dept. Frontiers in Engineering Innovation Judd Distinguished Lecture Dr. Alberto Sangiovanni-Vincentelli Buttner Chair Electrical and Computer Sciences University of California, Berkeley When: Wednesday, December 3, 2014 at 3:05 p.m.Where: Sorenson Molecular Biotechnology Building (SMBB) 2650 - Auditorium Abstract Giovan Battista Vico, a philosopher and historian who lived across the XVII and XVIII centuries, was the first to note in his masterpiece “Scienza Nuova” (New Science) that the history of man and his endeavors follow a cyclical pattern. Economies, as well as the power of nations, have exhibited a clear and cyclical behavior. Electronic Design Automation (EDA) has not escaped this fundamental law. EDA started in the late 1960s when large companies such as IBM and Bell Laboratories were developing new products based on Integrated Circuit technology. The ICs of the time had only a few tens of transistors but the design costs were raising and the need to obtain circuit right the first time became clear. The scientific content of tools and methods for ICs ranged from physics to mathematics in a mix that is rare to see in any other engineering field. EDA technology advances have oscillated between verification and synthesis, the perception in the mind of the electronic design community of EDA has been rising and falling in a regular pattern, EDA companies have risen and declined, the consideration of the financial community for EDA has been periodically increasing and decreasing, and the algorithms used in EDA have swung from general purpose techniques borrowed from mathematics, computer science, operation research, and artificial intelligence, to ad hoc techniques that leverage the nature of the specific design problem to be solved. I will show that progress is achieved when new methodologies crystallize, with new tools and techniques acting as catalysts, that the construction of layers of abstraction are the steps that have helped us reach new heights, that the progress of EDA technology has slowed down just when complexity has reached levels never seen before. I will argue that the designer community must leave its traditional shores, under attack by the swarm of killer transistors (more than 1 Billion transistor circuits have been realized), and sail towards a new world where transistors have been tamed. The advances in technology have made it possible to dream about a “smart planet” where trillions of devices are available for humanity. Throughout the talk I will intersperse considerations about my scientific and industrial journey from theory oriented professor to “entrepreneur.” Biography Alberto Sangiovanni-Vincentelli holds the Buttner Chair of Electrical Engineering and Computer Sciences, University of California, Berkeley.
