  • Via-only microwave/millimeter wave bandpass filters for LTCC applications

    Creator:
    Bhargava, Gaurav
    Abstract:
    With an increasing number of wireless applications at microwave frequencies, the frequency spectrum is becoming quite crowded. Due to this congestion, the current state of technology is leading towards upper microwave and millimeter wave spectra as they also offer other distinct advantages such as larger bandwidth and smaller component footprint....

  • Variable sampling compensation of networked control systems with delays using neural networks

    Creator:
    Lopez-Echevarria, Daniel
    Abstract:
    In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...

  • Urban military operation mobility model

    Creator:
    Kang, Ho Sung
    Abstract:
    A Mobile Ad-hoc NETwork (MANET) is collection of wireless mobile nodes without a network infrastructure or centralized administration. Although MANETs can be used in many applications, such as mobile Internet, military communication, and disaster relief networks, a number of challenges remain. These include routing, medium access control, security, scalability, energy...

  • Understanding the ultra-wideband channel within a computer chassis

    Creator:
    Redfield, Stephen J.
    Abstract:
    Recent developments in computing technology have generated a demand for more streamlined and effective test systems. By replacing traditional in-chassis wired interconnects with a broadcast wireless system, fault detection and error susceptibility will drastically improve, input/output capabilities will expand, and routing complexity will decrease. Ultra-wideband impulse radio's (UWB-IR) characteristic multipath-immunity...

  • Ultra-low power receivers for wireless sensor networks

    Creator:
    Ayers, James S.
    Abstract:
    In wireless sensor network applications, low-power operation of the wireless receiver is critical. To address this need an ultra-low power Binary Frequency Shift Keying (BFSK) receiver using the super-regenerative architecture is developed. A prototype receiver is built and tested for operation in the 900 MHz ISM band. Lab measurements show...

  • Ultra low capacitance RFIC probe

    Creator:
    Jacob, Michael E.
    Abstract:
    In Radio Frequency Integrated Circuits (RFIC) or high frequency digital ICs, there is a demand to probe the internal nodes for testing. The ultra low capacitance RFIC probe presented in his work is a flexible tool for these applications. The probe utilizes the coupling between a tungsten needle and the...

  • Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

    Creator:
    Guerber, Jon
    Abstract:
    In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...

  • The Architecture of a Reusable Built-In Self-Test for Link Training, IO and Memory Defect Detection and Auto Repair on 14nm Intel SOC

    Creator:
    Querbach, Bruce
    Abstract:
    The complexity of designing and testing today's system on chip (SOC) is increasing due to greater integrated circuit (IC) density and higher IO and memory frequencies. SOCs for the mobile phone and tablet market have the unique challenge of short product development windows, at times less than six months, and...

  • Surface-Normal Modulation of Fano Resonances in Metallic Photonic Crystals for Free-Space Optical Interconnects

    Creator:
    Ren, Fanghui
    Abstract:
    This dissertation focuses on the development of ultra-compact optical devices for free-space modulation. We propose a surface-normal modulator using metallic photonic crystals for free-space optical interconnects. The active control of light intensity is achieved by engineering the Fano resonances in metallic photonic crystals. Both thermo-optic modulation and electro-optic modulation of...
