  • A comparison of substrate noise coupling in lightly and heavily doped CMOS processes for 2.4 GHz LNA's

    Creator:
    Hazenboom, Duncan S.
    Abstract:
    Three types of low noise amplifiers operating at 2.4GHz were designed. They are the commonly used single-ended and differential amplifiers as well as a new quasi-differential amplifier. The substrate noise injected into these amplifiers is examined for both heavily and lightly doped CMOS substrates. For the single-ended amplifier the noise...

  • CAM : a new Circuit Augmentation Method for modeling interconnects and passive components

    Creator:
    Kolstad, Joel W.
    Abstract:
    Contemporary circuit design involves significant computer-based simulation, calling for a balance between circuit model accuracy and simulation run time. Traditionally, circuit modelers concentrated on producing either (1) physically-based models, where each element in the model correlates to a physically meaningful aspect of the device being modeled or (2) mathematically-based "macromodels,"...

  • Low cost, short wavelenght fiber Bragg grating strain sensor systems

    Creator:
    Vaughan, Lira
    Abstract:
    Fiber Bragg grating sensors have been constantly researched for the last ten years and have finally begun to find use in the commercial market. However, one of the major factors limiting their widespread use is their system cost. Their lightweight, flexibility, electromagnetic immunity, and small size make fiber Bragg grating...

  • Characteristics of semi-insulating GaAs photoconductive detectors under steady state illumination

    Creator:
    Yang, Howard C.
    Abstract:
    The optical and electrical characteristics of semi-insulating GaAs photoconductive detectors made with ohmic and Schottky contacts are studied in this thesis. Current - voltage measurements are made both in the dark and under varying power levels of HeNe laser (6328 Å) illumination. DC photocurrent gain is then calculated as a...

  • Wide stripe, high power diode lasers

    Creator:
    Parson, Kevin J.
    Abstract:
    Typical power outputs of commercially available diode lasers are on the order of 5 milliwatts. This thesis discusses the growth, processing and fabrication of high power (lOO's of milliwatts) diode lasers. Devices were grown by Molecular Beam Epitaxy (MBE) and by Metal Organic Chemical Vapor Deposition (MOCVD). The MOCVD diode...

  • A study of the photoresponse of semi-insulating gallium arsenide

    Creator:
    Schumm, Gerhard
    Abstract:
    The photoresponse behavior of semi-insulating GaAs is investigated. The photocarrier lifetime is discussed and the influence of surface and contact recombination is taken into account. Photocurrent-voltage characteristics have been measured and a mechanism for the gain in terms of space charge amplification and avalanching is suggested. The influence of deep...

  • Fiber Bragg grating-tunable diode laser

    Creator:
    Ericksen, Doug
    Abstract:
    Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the development and fabrication of such a device. An introduction is given describing applications of tunable lasers and some of the different methods of creating a tunable diode...

  • Deep ultraviolet solid-state laser development

    Creator:
    Dutton, David A. (David Adam)
    Abstract:
    There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...
