Talk Title: Fundamental Limits on Noise Performance of VCO-Based ADCs
Series: Integrated Systems Seminar
Abstract: Low-cost energy-efficient analog-to-digital converters (ADCs) are needed in many rapidly growing mixed-signal application areas such as wireless communication, autonomously powered sensing and monitoring nodes, and implanted biomedical devices for assistive technology. In systems constrained by battery power or scavenged energy limits, ADC energy efficiency as expressed by the fJ/step figure-of-merit is a critical design driver. Scaling of CMOS to nanometer dimensions has enabled dramatic improvement in digital power efficiency; however, most traditionally dominant ADC architectures are not well suited to the lower supply voltage environment. The improvement in time resolution enabled by increased digital speeds naturally drives design toward time-domain ADC architectures such as voltage-controlled-oscillator (VCO) based ADCs. Despite much recent work on techniques to improve SNR performance, the overhead of additional circuitry to mitigate VCO nonlinearity imposes a power penalty that has until now kept efficiency performance far above the minimum capability of the VCO-based approach. This talk will begin with a brief overview of the VCO-based approach and previous techniques to improve linearity in VCO-based ADCs. Next, the talk covers application of the "split ADC" architecture to enable lookup-table (LUT) based digital background calibration for a family of reconfigurable VCO-based ADCs in 28nm CMOS, targeting sample rates from 1 to 300 MSps and resolutions of 8 to 14 bits. Finally, work on fundamental sources of VCO jitter will be applied to determine the ultimate limit on performance for techniques such as VCO-based ADCs which perform the ADC function in the time domain.
Biography: John McNeill received his bachelor's degree from Dartmouth College in 1983, M.S. from the University of Rochester in 1991, and Ph.D. from Boston University in 1994. From 1983 to 1990 he worked in industry in the design of high speed, high resolution analog-to-digital converters and low noise interface electronics used in wide dynamic range imaging systems. In 1994, he joined Worcester Polytechnic Institute, in Worcester, Massachusetts, where he now is a Professor and Associate Head in the Electrical and Computer Engineering department. In 1999 he received WPI's Award for Outstanding Teaching. In 2006, with co-authors Michael Coln and Brian Larrivee of Analog Devices, he received the Lewis Winner award for Best Paper at the 2005 ISSCC. His research interests are in the areas of low-jitter VCO design and self-calibrating analog-to-digital converters.

NL Seminar- Automated Deep Multi-Phenotyping with Noisy Labels
Fri, Sep 25, 2015 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: David Kale, USC/ISI
Talk Title: Automated Deep Multi-Phenotyping with Noisy Labels
Series: Natural Language Seminar
Abstract: The increasing volume of electronic health records (EHR) data has spurred significant interest in the development of algorithmic phenotyping, used to identify patient cohorts in massive databases. Data-driven phenotyping, which formulates phenotyping as a statistical learning problem, offers superior scalability and generalization. Building upon previous work at Stanford, we propose a deep multi-phenotyping model: we train a single multi-task neural network to recognize multiple phenotypes, trained on noisy labels generated via an automatic process. We present preliminary results on classifying over 30 different phenotypes on a data set of over one million patients from the Stanford clinical system. This is joint work with Nigam Shah at Stanford University Center for Biomedical Informatics Research.
Biography: Dave Kale is a fourth year PhD student in Computer Science and an Alfred E. Mann Innovation in Engineering Fellow at the University of Southern California. He is advised by Greg Ver Steeg. Before joining USC and ISI, he worked in the Whittier VPICU at Children's Hospital LA and co-founded the Meaningful Use of Complex Medical Data (MUCMD) Symposium. Dave holds a BS and MS from Stanford University.
Host: Nima Pourdamghani and Kevin Knight
