Signal processing techniques for the mixed-signal circuit designer

Ming Hsieh Department of Electrical and Computer Engineering
University Calendar
Sudhakar Pamarti - UCLAAbstract: Mixed-signal circuits are critical components in most electronic systems. Aggressive integrated circuit technology scaling has placed on them both tremendous performance demands and severe challenges such as transistor non-linearity, process variability etc. This talk will present a choice selection of signal processing techniques that exploit the relative abundance of inexpensive digital logic to overcome the aforementioned challenges and enable high performance in mixed-signal circuits. Specifically, techniques that "condition" the statistical properties of signals being processed by the mixed-signal circuits, making them inherently immune to circuit imperfections, will be described. Example applications to frequency synthesizers, power amplifiers, and wired communication transceivers will be presented.Biography: Sudhakar Pamarti is an assistant professor of electrical engineering at the University of California, Los Angeles, where he teaches and conducts research in the fields of mixed-signal circuit design and signal processing. Dr. Pamarti received the M.S. and the Ph.D. degrees in electrical engineering from the University of California at San Diego in 1999 and 2003, respectively, and the Bachelor of Technology degree in electronics and electrical communications engineering from the Indian Institute of Technology, Kharagpur in 1995. Prior to joining UCLA, he has worked at Rambus Inc. ('03-`05) and Hughes Software Systems ('95-`97) developing real-time, embedded software and firmware for a wireless-in-local-loop communication system. Dr. Pamarti is a recipient of the NSF CAREER award. He currently serves on the editorial board of the IEEE Transactions on Circuits and Systems II.

Graphene and Carbon Nanotube Electronics: Device Physics and Simulation

Jing Guo - University of FloridaAbstract: In recent years, significant progress has been achieved in graphene and carbon nanotube
(CNT) electronics. In a graphene or carbon nanotube, low bias transport can be nearly ballistic.
Deposition of high-ê gate insulators does not degrade the carrier mobility because of an absence of
dangling bonds. The conduction and valence bands are symmetric, which is advantageous for
complementary applications. The Excellent transport property promises high-speed transistor
applications. Carbon-based nanostructures are receiving much attention for possible device applications.
We have developed a self-consistent atomistic simulator for graphene and CNT field-effect transistors
(FETs) based on the non-equilibrium Green's function (NEGF) formalism, and applied it to understand
and explain experiments. The simulator provides an atomistic scale description for quantum transport in
the presence of inelastic scattering and electron-photon interaction. We show that CNTFET is capable of
delivering a near ballistic DC on-current even under high source-drain bias conditions. The radio
frequency (RF) characteristics of CNTFETs are simulated for understanding potential high-speed
transistor applications. On graphene electronics, we show that edge chemistry of graphene nanoribbons
(GNRs) provides promising opportunities to engineer the device properties. Device physics and design
options of GNR-based tunneling transistors are also examined by atomistic device simulations.Biography: Jing Guo received the Ph.D. degree in electrical engineering from Purdue University, West
Lafayette, IN, and subsequently joined University of Florida as an assistant professor in Aug. 2004. His
research interests focus on modeling and simulation of nanoscale devices with applications in electronics and
optoelectronics, in close collaboration with experimentalists. He has published over sixty peer-reviewed
journal papers on prestigious journals including Science, Nature, Phys. Rev. Lett., Nano Lett., Appl. Phys.
Lett., Nature Nanotechnology, and IEEE Transactions. He is a recipient of the National Science Foundation
(NSF) Faculty Early CAREER Award, and served in the technical program committee of International
Electron Device Meeting (IEDM) and Device Research Conference (DRC). He is the coauthor of the book,
"Nanoscale Transistors: Device Physics, Modeling, and Simulation" published by Springer.Location: Hughes Aircraft Electrical Engineering Center (EEB) - 248
