  • Comparison and impact of substrate noise due to clocked and clockless circuitry

    Creator:
    Le, Jim K.
    Abstract:
    Delay insensitive asynchronous circuitry provides significant advantages with respect to substrate noise due to localized switching. The differences between the substrate noise from NULL Convention Logic (NCL) and traditional Clocked Boolean Logic (CBL) are described and analyzed based on measured results. A test chip fabricated in the TSMC 0.25 um...

  • Analysis and synthesis of neural networks

    Creator:
    Skelton, Jeanette K.
    Abstract:
    The brain has long attracted the interest of researchers. Some tasks, such as pattern recognition and optimization, have proven to be exceptionally difficult for conventional computing systems to perform, but are executed by the brain almost effortlessly. Due to the large number of neurons and interconnections, it has proven impossible...

  • Active power filter for the cancellation of harmonic line current distortion

    Creator:
    Merk, Marcel
    Abstract:
    With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the generation of nonsinusoidal currents in the power distribution network due to the nonlinear operation. Harmonic currents may distort...

  • Design of a 14-bit continuous-time Delta-Sigma A/D modulator with 2.5MHz signal bandwidth

    Creator:
    Li, Zhimin
    Abstract:
    In recent years, there has been growing interest in both industry and academia to use continuous-time (CT) Δ-Σ A/D converters for wideband wireless and wireline communication applications. So far no reported CT Δ-Σ A/D modulator achieves 14-bit or higher dynamic range (DR) with more than 2MHz signal bandwidth (equivalently 4MS/s)....

  • Low-power design techniques for low-voltage analog-to-digital converters

    Creator:
    Kim, Min Gyu
    Abstract:
    The demand for portable electronic systems and the continued down-scaling of device dimensions resulted in rapid improvement in the performance of integrated systems. Several low-voltage design techniques have been proposed to operate analog circuits with sub-1V supply. However, these techniques require higher power consumption to achieve large dynamic range while...

  • Space time coding in MIMO systems

    Creator:
    Xian, Liang
    Abstract:
    Multiple-input multiple-output (MIMO) antenna technology is promising for high-speed wireless communications without increasing the transmission band- width. Space time coding (STC) is a scheme that employs multiple antennas to increase transmission rate or to improve transmission quality. STC is used widely in mobile cellular networks, wireless local area networks (WLAN)...

  • Electronic device and nanolaminate application of amorphous metal thin films

    Creator:
    Cowell, E. William, III
    Abstract:
    The objective of this dissertation is to develop amorphous metal thin films (AMTFs) for two-terminal electrical device and nanolaminate applications. Two AMTFs, ZrCuAlNi and TiAl, are investigated in both two-terminal electrical device and nanolaminate applications. Material properties including composition, atomic order, surface morphology, surface potential, and electrical resistivity are explored....

  • Investigation of metal-insulator-metal (MIM) and nanolaminate barrier MIIM tunnel devices fabricated via atomic layer deposition

    Creator:
    Alimardani, Nasir
    Abstract:
    Metal-insulator-metal (MIM) tunnel devices have been proposed for high speed applications such as hot electron transistors, IR detectors, optical rectennas for IR energy harvesting, and backplanes for LCDs. The majority of these applications require highly asymmetric and non-linear current versus voltage (I-V) behavior at low applied voltages and ultra-high frequencies....

  • Thermally-stable amorphous metal thin films

    Creator:
    McGlone, John M.
    Abstract:
    Amorphous metal thin films (AMTFs) are of potential use for metal-insulator-metal (MIM) tunnel diode applications due to their ultra-smooth surfaces, a consequence of their amorphous microstructure. The objective of this thesis is to design a thermally-stable AMTF capable of maintaining MIM tunnel diode performance after a post-deposition anneal in excess...
