Nanoelectronics: Technology Assessment and Projection at the Device, Circuit and System level
Mon, Mar 01, 2010 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Presented by Lan WeiAbstract:
Nowadays, physical gate length can no longer be effectively scaled down and traditional boosters (e.g., strain, high-k/metal gate) are exhibiting diminishing returns on performance improvement. Continued progress in nanoelectronics necessitates a holistic view across the boundaries of device, circuit and system domains. The best devices are those that are optimized for the circuits and systems of the target application. Device design and engineering must aim at improvements at the circuit and system levels.
In this talk, the design space is explored for future Si CMOS technology and for carbon nanotube field effect transistors, a promising technology in the post-Si era. Compact models for transport properties and capacitive components of different device structures have been developed to facilitate circuit-level analysis and system-level optimization. Possible ways of extending the technology roadmap are proposed. We propose scenarios of selective device structure scaling that will enable Si CMOS technology scaling for several generations beyond the currently perceived limits. Beyond Si CMOS scaling, carbon nanotube field effect transistors (CNFETs) are optimized and projected to achieve 5x chip-level speed up over PDSOI at 11 nm technology node for a high-performance four-core processor with 1.5M logic gates.

Towards Integrated Nanoscale Systems
Tue, Mar 02, 2010 @ 03:00 PM - 04:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Presented by Jeff WeldonAbstract:
Nanotechnology has been recognized for its tremendous potential to produce smaller, more efficient and more cost-effective systems. The ability to control materials at the atomic and molecular scale has generated opportunities in a variety of disciplines including engineering, computer science, biology, physics and chemistry. However, realizing the potential of nanotechnology for systems-level applications requires a fundamental understanding of both the system requirements and the capabilities of the underlying nanoscale material. One promising nanoscale material is the carbon nanotube, a material with exceptional electrical and mechanical properties.This talk will demonstrate how rethinking the fundamental nature of systems and electronics can lead to dramatically smaller and potentially more capable solutions. The presentation will begin with a discussion of a traditional design approach in which a CMOS integrated circuit was designed to facilitate system-on-a-chip integration. To leverage the benefits of novel nanoscale devices and improve upon current technology, a paradigm shift, away from standard block-level design, will be needed. To facilitate this shift requires a thorough understanding of the new nanoscale materials and devices. As an example, we will discuss how a single carbon nanotube can be designed to function as a complete radio receiver. In addition, we will present a novel nanoelectromechanical oscillator with the potential for significant size reduction and improved performance compared with current solutions. Biography:

Security in Large Wireless Networks
Wed, Mar 10, 2010 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dennis Goeckel,
Electrical and Computer Engineering,
University of Massachusetts - AmherstAbstract: Recently, there has been significant interest in providing secure communication in wireless networks. Here we consider the challenge of providing information theoretic secrecy in the presence of eavesdroppers, and, in contrast to prior work, focus in particular on the difficulty that arises due to a lack of knowledge of the eavesdropper location. To combat the resulting "near eavesdropper" problem, we employ cooperative jamming to confuse the eavesdropper and multi-user diversity to find relays that receive the packet in the presence of such jamming. For an environment with a single source and destination, along with N system nodes, we consider the number of eavesdroppers that can be tolerated for both the case when eavesdroppers do potentially have a significant geographical advantage over the receiver, and when they do not. Next, we consider multipair unicast transmission in large networks with n source-destination pairs and demonstrate an achievable tradeoff between the per-session througput of the system and the tolerable intensity of eavesdroppers.Biography: Dennis Goeckel split time between Purdue University and Sundstrand Corporation from 1987-1992, receiving his BSEE from Purdue in 1992.

Xampling -- Analog-to-digital at Sub-Nyquist rates
Wed, Mar 10, 2010 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Yonina Eldar,
Electrical Engineering,
Technion, IsraelAbstract: CSignal processing methods have changed substantially over the last several decades. The number of operations that are shifted from analog to digital is constantly increasing. While technology advances enable mass processing of huge data streams, the acquisition capabilities do not scale sufficiently fast so that the conversion to digital has become a serious bottleneck. For some applications, the maximal frequency of the input signals, which dictates the Nyquist rate, already exceeds the possible rates achievable with existing devices.In this talk, we present a new framework for sampling wideband analog signals at rates far below that dictated by the Nyquist rate. We refer to this methodology as Xampling: A combination of compression and sampling, performed simultaneously. Xampling merges results from standard sampling theory with recent developments in the field of compressed sensing in order to directly sample a wide class of analog signals at very low rates using existing hardware devices. This paradigm relies on exploiting structure inherent to many different classes of signals, which can be modeled mathematically as a union of subspaces.We begin by introducing the Xampling methodology and explaining why both sampling and compressed sensing alone are insufficient to address low rate sampling of a wide variety of analog signals. We then consider some specific examples including low rate sampling of multiband signals and recovery of time delays from low rate samples.Biography: Yonina C.

Photonics Seminar: Resonant single sideband modulators
Thu, Mar 11, 2010 @ 01:00 PM - 02:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Dr. Andrey Matsko, OEwaves Inc.Abstract: Optical modulators up-convert RF signals to the optical domain and are key components in all microwave photonics applications. Modulators that have a very large bandwidth are naturally desired in wideband applications. This is generally obtained at the expense of lower power efficiency. Unlike standard wideband lithium niobate and electro-absorption varieties, modulators in narrowband microwave photonics feature extremely high efficiency. The high efficiency is obtained with resonance coupling to RF electrodes and/or the use of optical resonance devices. This approach leads to filtering, in addition to light modulation, which is desirable in virtually all narrowband applications. Here we present a new class of modulators with the unique feature of providing a narrow modulation bandwidth over a very wide RF frequency range. This feature opens up new and compelling applications such as widely tunable microwave photonic receivers as well as tunable opto-electronic oscillators.Bio: Dr. Andrey Matsko is an internationally recognized expert in theory of whispering gallery mode micro-resonators as well as quantum and nonlinear optics. He has over 100 journal publications in the fields and holds 12 US patents. He is a Principal Engineer at OEwaves Inc., where he is involved in studies of properties and applications of whispering gallery modes in dielectric optical resonators. Previously, being employed as a principal member of technical staff at Jet Propulsion Laboratory (JPL), he has initiated, participated, and led theoretical investigations of RF photonic receivers, miniature electro-optical modulators, opto-electronic oscillators, and tunable narrowband filters. He has studied and developed theoretical models based on which novel types of whispering gallery mode resonators with novel functionalities have been produced. He has investigated and developed models for noise and stability parameters of novel oscillators based on linear and nonlinear properties of whispering gallery mode resonators.

Long-Term Context Modeling for Acoustic- Linguistic Emotion Recognition
Thu, Mar 11, 2010 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract:
The automatic estimation of human affect from the speech signal is an important step towards making virtual agents more natural and human-like. Thus, we present a novel technique for incremental recognition of the
user's emotional state as it is applied in a Sensitive Artificial Listener (SAL) system, designed for socially competent human-machine communication. Our method is capable of using acoustic, linguistic, as well as long-range contextual information in order to continuously predict the current quadrant in a two-dimensional emotional space spanned by the dimensions valence and activation. The main system components are a hierarchical Dynamic Bayesian Network for detecting linguistic keyword features and Long Short-Term Memory recurrent neural networks which model phoneme context and emotional history to predict the affective state of the user. We evaluate various keyword spotting model architectures for linguistic feature generation as well as different strategies for extracting relevant acoustic features from the speech signal. Conducting experiments on the SAL corpus of non-prototypical real-life emotional speech, we obtain a quadrant prediction accuracy that is comparable to the average inter-labeler consistency.

A Process Variation Perspective on 3D Integration

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Siddharth Garg,
Carnegie-Mellon UniversityAbstract:
3D integration is a promising emerging technology that offers increased system integration by vertically integrating multiple planar die. In addition, 3D integration provides lower communication latency and greater bandwidth between system components, potentially addressing the increased on-chip communication costs that accompany technology scaling. However, emerging technologies must also be critically evaluated to identify potential pitfalls. From this perspective, the elevated thermal profile of 3D integrated circuits (ICs) has already been identified as a cause for concern. In this talk, I will demonstrate that the impact of manufacturing process variations on the performance of 3D circuits is another emerging cause for concern and discuss promising solutions to this problem.I will begin by presenting 3D-GCP, a high-level model for the impact of process variations on 3D IC performance. Using this model I will show that, in fact, 3D ICs suffer greater performance degradation under the impact of process variations compared to equivalent 2D implementations.
Furthermore, the performance hit is more severe as the number of layers in the 3D stack is increased, potentially eliminating any of performance benefits of 3D integration. Motivated by these predictions, I will present a novel process variation aware 3D assembly strategy that uses post-fabrication test data to maximize the number of assembled systems that meet a specified performance target. Experimental results on both application-specific and general purpose multi-core platforms demonstrate that significant performance yield improvements are achieved using the proposed techniques.Biography:

Architectural Inference and the Pursuit of Efficiency

Ming Hsieh Department of Electrical and Computer Engineering

Benjamin Lee,
Stanford UniversityAbstract:
Energy efficiency is a defining challenge in modern computing. Limits in technology scaling pose challenges in power density while limits in software parallelism raise questions about future multi-core integration. Without process and parallelism to drive efficiency, we must rely on specialization and design coordination across the hardware/software interface. However, specialization is prohibitively expensive, incurring high non-recurring engineering costs that arise from an intractable number of degrees of freedom. I present the case for architectural inference to provide tractability for complex design questions in computer architecture. Inference enables comprehensive solutions to long-standing and previously intractable design priorities in heterogeneous specialization, application/architecture co-design, and architecture/circuit co-design. I also describe strategies for leveraging efficient components in cloud computing systems. In particular, I discuss experiences from deploying the Microsoft Bing search engine on mobile processors for energy efficiency. I also note the price of efficiency, which is exacted from application robustness and flexibility, and the implications for future system design. Biography:
Benjamin Lee is an NSF Computing Innovation Fellow in Electrical Engineering and a member of the VLSI Research Group at Stanford University.

Large tuning of birefringence in two strip silicon waveguidesvia optomechanical motion Jing Ma An optomechanical method is presented to tune phase birefringence in parallel silicon strip waveguides. We first calculate the deformation of suspended, parallel strip waveguides due to optical forces. We optimize the frequency and polarization of the pump light to obtain a 9nm deformation for an optical power of 20mW. Widely tunable phase birefringence can be achieved by varying the pump power, with maximum values of 0.026. The giant phase birefringence allows linear to circular polarization conversion within 30µm for a pump power of 67mW. In-Plane Thermally Tuned Silicon-on-Insulator Wavelength Selective ReflectorLawrence StewartThe transparency of silicon at communications wavelengths makes it an ideal choice for low loss optical devices; however, silicon suffers from few and comparatively weak tuning methods. Free carrier injection or depletion are widely used and are suitable for high speed modulators, but these devices are ultimately limited by free carrier induced absorption effects. While a much slower process, thermal tuning allows for large refractive index changes with minimal changes in optical absorption. A thermally tunable silicon-on-insulator wavelength selective reflector is proposed for an application as a mirror in an integrated tunable laser. Simulations and recent experimental results of thermally tuned microring devices will be presented.

With power and cooling becoming an increasingly costly part of the operating cost of a server, the old trend of striving for higher performance with little regard for power is over. Emerging semiconductor process technologies, multicore architectures, and new interconnect technology provide an avenue for future servers to become low power, compact, and possibly mobile. In our talk we examine three techniques for achieving low power: 1) Near threshold operation; 2) 3D die stacking; and 3) replacing DRAM with Flash memory.Lecture 4:00PM

Conferences, Lectures, & Seminars
Nicole Nelson, University of MarylandAbstract: Biosensors for lab on a chip and portable applications typically detect weak signals while having limited power resources. These sensors must therefore be carefully designed while accounting for the noise performance. I will show a methodology, based on the classical Shannon capacity, of formulating the tradeoffs in energy and power resources, intrinsic noise and signal power. In particular I model analog circuits as communication channels corrupted by noise and will show the model thus far for operational transconductance amplifiers as well as an active pixel sensor. In addition I will show results of a bioamplifier which measures weak extra- cellular signals of electrogenic cells as well as a handheld fluorometer that can be used for a variety of biological applications.Biography: Nicole Nelson received her Bachelor's and Master's degree from Howard University in 2001 and 2003 respectively and is currently completing her PhD at the University of Maryland,College Park.

Mike Shuo-Wei ChenAbstract:
Over the years, the main stream CMOS technology has been scaling in favor of digital circuits at an explosive speed. It imposes increasing design constraints for analog circuits, such as lower supply voltages, lower gain, leakage currents, and noise, etc. On the other hand, the future radios will demand higher complexity and tighter circuit specifications. Driven by these trends, a new design philosophy is proposed to redefine analog circuit topologies that involve an architectural rethinking, utilizing almost free digital circuits and faster device speed. In this talk, we will examine such opportunities specifically in the mixed-signal IC area. We will use phase locked loop (PLL) and analog-to-digital converter (ADC) as case studies, which are critical components to enable future complex system-on-chip (SOC) and mostly-digital system architectures. In both cases, the performance and cost are substantially improved by adopting the new design philosophy.Biography:
