  • Krishna, Tushar (Massachusetts Institute of Technology, 2014)
    Adding multiple processing cores on the same chip has become the de facto design choice as we continue extracting more and more performance/watt from our chips in every technology generation. In this context, the interconnect ...
  • Orji, Uzoma A (Massachusetts Institute of Technology, 2014)
    The U.S. Department of Energy has identified "sensing and measurement" as one of the "five fundamental technologies" essential for driving the creation of a "Smart Grid". Consumers will need "simple, accessible..., rich, ...
  • Georgas, Michael S. (Michael Stephen) (Massachusetts Institute of Technology, 2014)
    Integrated photonics has emerged as an I/O technology set to disrupt the communication fabric of many-core computer systems. The optical technology uses wavelength-division-multiplexing and a high degree of integration in ...
  • Krieger, James David, 1978- (Massachusetts Institute of Technology, 2014)
    Digital techniques have had longstanding use in both the operational control and signal processing efforts associated with phased array antennas. Fundamentally, these techniques have served to provide additional levels of ...
  • Lestoquoy, Guillaume (Massachusetts Institute of Technology, 2014)
    As the number of materials that are thermally-drawable into fibers is rapidly expending, numerous new multimaterial fiber architectures can be envisioned and fabricated. High-melting temperature metals, compound materials, ...
  • Markova, Mariana (Mariana T.) (Massachusetts Institute of Technology, 2014)
    Technology scaling poses challenges in designing analog circuits because of the decrease in intrinsic gain and reduced swing. An alternative to using high-gain amplifiers in the implementation of switched-capacitor circuits ...
  • Boyd-Wickizer, Silas (Massachusetts Institute of Technology, 2014)
    One difficulty of programming multicore processors is achieving performance that scales with the number of cores in the system. A common performance optimization is to increase inter-core parallelism. If the application ...
  • Chung, SungWon, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2014)
    The continued improvement of transistor performance has increased the limit on the peak energy-efficiency of wireless transmitters. Nevertheless, the average efficiency with mobile multimedia communication is decreasing ...
  • Goswami, Sushmit (Massachusetts Institute of Technology, 2014)
    The desire for ubiquitous connectivity is pushing radios towards highly-integrated, multi-standard and multi-band implementations. This thesis explores architectures for next-generation RF frontends, which form the interface ...
  • Kao, Tsung-Yu (Massachusetts Institute of Technology, 2014)
    The terahertz (THz) frequency range (300 GHz to 10 THz, wavelength 30-1000 [mu]m), despite having many potential applications, is technologically relatively underdeveloped mainly because of the lack of suitable coherent ...
  • Lee, Dong Seup (Massachusetts Institute of Technology, 2014)
    Due to the unique combination of large critical breakdown field and high electron velocity, GaN-based high electron mobility transistors (HEMTs) have great potential for next generation high power RF amplifiers. The ...
  • Lee, Sunghyuk (Massachusetts Institute of Technology, 2014)
    Analog-to-digital converters (ADCs) are essential building blocks in many electronic systems which require digital signal processing and storage of analog signals. Traditionally, ADCs are considered a power hungry circuit. ...
  • Li, Duo, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2014)
    Photonic microwave oscillator based on optical frequency comb and ultrastable optical reference cavity represents the state-of-the-art solution to generate X-band microwaves of ultralow phase noise. Such high-quality ...
  • Liu, Jonathan Jaoshin (Massachusetts Institute of Technology, 2014)
    Optical coherence tomography (OCT) is a non-contact, non-invasive, micron-scale optical imaging technology that has become a standard clinical tool in ophthalmology. Fourier domain OCT detection methods have enabled higher ...
  • Grosse, Roger Baker (Massachusetts Institute of Technology, 2014)
    We often build complex probabilistic models by composing simpler models-using one model to generate parameters or latent variables for another model. This allows us to express complex distributions over the observed data ...
  • Ansel, Jason (Jason Andrew) (Massachusetts Institute of Technology, 2014)
    The process of optimizing programs and libraries, both for performance and quality of service, can be viewed as a search problem over the space of implementation choices. This search is traditionally manually conducted by ...
  • Brookshire, Jonathan David (Massachusetts Institute of Technology, 2014)
    Outside the factory, robots will often encounter mechanical systems with which they need to interact. The robot may need to open and unload a kitchen dishwasher or move around heavy construction equipment. Many of the ...
  • Chen, Kailiang (Massachusetts Institute of Technology, 2014)
    This work presents a scalable Column-Row-Parallel ASIC architecture for 3D wearable / portable medical ultrasound. It leverages programmable electronic addressing to achieve linear scaling for both hardware interconnection ...
  • Santhanam, Parthiban (Massachusetts Institute of Technology, 2014)
    Thermo-electric heat exchange in semiconductor light emitting diodes (LEDs) allows these devices to emit optical power in excess of the electrical power used to drive them, with the remaining power drawn from ambient heat. ...
  • Rubinstein, Michael, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2014)
    Our world is constantly changing, and it is important for us to understand how our environment changes and evolves over time. A common method for capturing and communicating such changes is imagery - whether captured by ...
