  • Ring Amplifier Design Techniques for High-Precision and High-Speed Amplification

    Creator:
    Leuenberger, Spencer
    Abstract:
    Demands of today's integrated society dependent on communication systems have driven the creation of ever more efficient analog-to-digital converters. For the same reasons, digital circuitry has rapidly expanded to serve all the different systems and needs of consumers. The trend of technology development has been to make these digital circuits...

  • Information processing errors in linear feedback control systems

    Creator:
    Chong, Hoi-yeung
    Abstract:
    This report is concerned with the analysis of the effect of finite wordlength, channel capacity and source rate in digital feedback control of linear systems. The cases considered are (1) finite wordlength A/D conversion, no feedback delay, ideal ROM (read only memory) controller; (2) finite A/D wordlength (source rate), state...

  • Development of a 300 Hp regenerative motor and generator test facility

    Creator:
    Lewis, Timothy M. (Timothy Michael)
    Abstract:
    A 300 hp motor and generator testing facility is being completed at Oregon State University. The testing center is the largest independent testing facility west of the Mississippi River. This regional resource center will incorporate state-of-the-art features that set it apart from other testing facilities. An induction machine with a...

  • Growth, fabrication and modeling of pseudomorphic laser diodes

    Creator:
    Ebner, John
    Abstract:
    This thesis reports on the crystal growth, fabrication, modeling and performance of Graded Index-Separate Confinement Heterostructure laser diodes which contain pseudomorphic InGaAs as the active region material. Laser epitaxial layers were grown with different indium mole-fractions, and a constant InGaAs layer thickness of 10 nm, on both sides of the...

  • Fully-differential current-mode CMOS circuits and applications

    Creator:
    Zele, Rajesh H.
    Abstract:
    With increasing interest in current-mode analogue processing due to its high performance properties such as speed, bandwidth and accuracy compared to voltage-mode processing, new current-mode alternatives to various conventional circuit designs are appearing. In this report, a novel circuit design to construct a fully-differential current-mode operational amplifier ( OP-AMP )...

  • Computing Substation Fragility as a Function of Seismic Component Failure

    Creator:
    Stark, William D.
    Abstract:
    The electrical grid of the Western Interconnection is vulnerable to earthquake damage, especially large-magnitude megathrust events, due to the unique seismic profile of the region. However, the size of the Western Interconnection makes it difficult to model seismic failure in electrical substations to the level of detail necessary to improve...

  • Growth, fabrication and testing of pseudomorphic P-channel GaAs/InGaAs/AlGaAs MODFETS

    Creator:
    Schulte, Donald W.
    Abstract:
    This thesis reports on the growth and characterization of p-type pseudomorphic A1GaAs /InGaAs /GaAs modulation doped field effect transistor (MODFET) structures. A series of different p-type MODFET structures were grown with a systematic variation of the indium mole fraction and quantum well width of the InGaAs channel region. Extensive characterization...

  • The growth of ternary compound semiconductors by molecular beam epitaxy

    Creator:
    Ebner, John
    Abstract:
    This thesis reports on an investigation of the growth, by Molecular Beam Epitaxy, of III,III-V ternary compound semiconductors. Strained and unstrained growth was studied via the deposition of InGaAs on GaAs and InP substrates. Lattice matched InGaAs on InP was grown, and an in situ method was developed to find...

  • Electo-optic characterization of ZnS:Tb ACTFEL devices for probing the hot electron distribution

    Creator:
    Streicher, Keone R.
    Abstract:
    In this report, the optical characteristics of ZnS:Tb AC driven thin-film electroluminescent devices are evaluated. Luminescence at low and room temperature under a constant phosphor field is recorded in order to probe the hot electron energy distribution. Samples fabricated by atomic layer epitaxy and by sputter deposition are investigated and...

  • Assessment of Barrier Heights between ZrCuAlNi Amorphous Metal and SiO₂, Al₂O₃, HfO₂, and ZrO₂ using Internal Photoemission Spectroscopy

    Creator:
    Klarr, Tyler D.
    Abstract:
    As scaling of silicon (Si) based devices approaches fundamental limits, thin film metal-insulator-metal (MIM) tunnel diodes are attracting interest due to their potential for high speed operation. Because operation of these devices is based on tunneling, electrode / interfacial roughness is critical. Recently, it was shown that combining ultra-smooth bottom...
