  • Kim, Dae-Hyun; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers, 2010-07)
    We present 30-nm InAs pseudomorphic HEMTs (PHEMTs) on an InP substrate with record fT characteristics and well-balanced fT and f[subscript max] values. This result was obtained by improving short-channel effects through ...
  • Kim, Tae-Woo; Kim, Dae-Hyun; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers, 2010-03)
    We have fabricated 30 nm In0.7Ga0.3As Inverted-Type HEMTs with outstanding logic performance, scalability and high frequency characteristics. The motivation for this work is the demonstration of reduced gate leakage current ...
  • Osgood, R. M.; Kimball, B. R.; Geis, Michael W.; Turner, George W.; Lyszczarz, Theodore M.; Molnar, Richard J. (SPIE, 2010-02)
    The optical switching times of liquid-crystal cells using 5CB, 5OCB and PCH5 liquid crystal materials have been characterized as a function of applied voltage, V, and temperature, T. The transition time from 90 to 10 % ...
  • Cho, Taeg Sang; Lee, Kyeong-Jae; Kong, Jing; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-01)
    This paper presents an energy-efficient chemical sensor system that uses carbon nanotubes (CNT) as the sensing medium. The room-temperature operation of CNT sensors eliminates the need for micro hot-plate arrays, which ...
  • Dawson, Joel L.; Chandrakasan, Anantha P.; Bohorquez, Jose L. (Institute of Electrical and Electronics Engineers, 2009-03)
    Recent advances in the medical field are spurring the need for ultra-low power transceivers for wireless communication with medical implants. To deal with the growing demand for medical telemetry, the FCC commissioned the ...
  • Kim, Jun Ki; Yun, Seok Hyun (Andy); Choi, Jin Woo (SPIE, 2013-04)
    Miniature endoscopic probes offer a solution for deep brain imaging by overcoming the limited depth of intravital microscopy. We describe a small-diameter (350 μm) graded-index optical probe with a side-view design for in ...
  • Snavely, Noah; Anderson, Ross W.; Cho, Peter L. (SPIE, 2010-04)
    Recent work in computer vision has demonstrated the potential to automatically recover camera and scene geometry from large collections of uncooperatively-collected photos. At the same time, aerial ladar and Geographic ...
  • Zorzos, Anthony Nicholas; Scholvin, Jorg; Boyden, Edward Stuart; Fonstad, Clifton G., Jr. (Optical Society of America, 2012-11)
    To deliver light to the brain for neuroscientific and neuroengineering applications like optogenetics, in which light is used to activate or silence neurons expressing specific photosensitive proteins, optical fibers are ...
  • Rivers, Alec Rothmyer; Durand, Fredo; Igarashi, Takeo (Association for Computing Machinery (ACM), 2010-07)
    We present a new sketch-based modeling approach in which models are interactively designed by drawing their 2D silhouettes from different views. The core idea of our paper is to limit the input to 2D silhouettes, removing ...
  • Yang, Zehong; Zhao, Xiaojun (Dove Medical Press, 2011-02)
    RADA16-I peptide hydrogel, a type of nanofiber scaffold derived from self-assembling peptide RADA16-I, has been extensively applied to regenerative medicine and tissue repair in order to develop novel nanomedicine systems. ...
  • Raskar, Ramesh; Agrawal, Amit; Chang, Ju Yong (Institute of Electrical and Electronics Engineers, 2009-08)
    We present a system for fast model-based segmentation and 3D pose estimation of specular objects using appearance based specular features. We use observed (a) specular reflection and (b) specular flow as cues, which are ...
  • Berdichevsky, Alina; Nedelcu, Simona; Boulias, Konstantinos; Bishop, Nicholas A.; Guarente, Leonard Pershing; Horvitz, H. Robert (National Academy of Sciences, 2010-11)
    Studies of long-lived Caenorhabditis elegans mutants have identified several genes that function to limit lifespan, i.e., loss-of-function mutations in these genes promote longevity. By contrast, little is known about ...
  • Spies, Noah; Burge, Christopher B.; Bartel, David (Cold Spring Harbor Laboratory Press, 2013-09)
    Variation in protein output across the genome is controlled at several levels, but the relative contributions of different regulatory mechanisms remain poorly understood. Here, we obtained global measurements of decay and ...
  • Paidimarri, Arun; Mercier, Patrick P.; Chandrakasan, Anantha P.; Nadeau, Phillip (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)
    A 2.4GHz TX in 65nm CMOS defines three channels using three high-Q FBARs and supports OOK, BPSK and MSK. The oscillators have -132dBc/Hz phase noise at 1MHz offset, and are multiplexed to an efficient resonant buffer. ...
  • Zellem, Robert T.; Knutson, Heather A.; Griffith, Caitlin A.; Showman, Adam P.; Fortney, Jonathan J.; Cowan, Nicolas B.; Agol, Eric; Burrows, Adam; Charbonneau, David; Deming, Drake; Laughlin, Gregory; Langton, Jonathan; Lewis, Nicole (IOP Publishing, 2014-07)
    The hot Jupiter HD 209458b is particularly amenable to detailed study as it is among the brightest transiting exoplanet systems currently known (V-mag = 7.65; K-mag = 6.308) and has a large planet-to-star contrast ratio. ...
  • Sinangil, Mahmut Ersin; Verma, Naveen; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-11)
    8T bit-cells hold great promise for overcoming device variability in deeply scaled SRAMs and enabling aggressive voltage scaling for ultra-low-power. This paper presents an array architecture and circuits with minimal ...
  • Grulkowski, Ireneusz; Jayaraman, Vijaysekhar; Cable, Alex E.; Kraus, Martin F.; Hornegger, Joachim; Duker, Jay S.; Fujimoto, James G.; Liu, Jonathan Jaoshin; Potsaid, Benjamin M. (SPIE, 2013-03)
