  • Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

    Creator:
    Trobough, Nathaniel D.
    Abstract:
    This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

  • Optimizing performance/watt of embedded SIMD multiprocessors through a priori application guided power scheduling

    Creator:
    Albright, Ryan K.
    Abstract:
    A method for improving performance/watt of an embedded single-instruction multiple-data (SIMD) architecture using application-guided a priori scheduling of hardware resources is presented. A multi-core architectural simulator is adopted that accurately estimates power, performance, and utilization of various processor components (logic, interconnect and memory). A greedy search is then performed on...

  • Interpolation-based digital quadrature frequency synthesizer

    Creator:
    Larson, Ryan John
    Abstract:
    Traditionally sinusoidal signal generation has been implemented with purely analog circuits such as phase-locked loops. The alternative of using a digital system to perform this signal generation has previously been unattractive due to limitations in clock frequency and size. However, recent advancements in sub-micron fabrication techniques have made the digital...

  • Area efficiency improvement of CMOS charge pump circuits

    Creator:
    Perigny, Ryan
    Abstract:
    In this thesis, the literature relating to charge pump dc-dc converters and their uses is reviewed. Charge pumps are useful in many circuits, including low-voltage circuits, dynamic random access memory circuits, switched-capacitor circuits, EEPROM's and transceivers. The important issues relating to charge pump design are power efficiency, output voltage ripple...

  • A study of hardware/software multithreading

    Creator:
    Carlson, Ryan L.
    Abstract:
    As the design of computers advances, two important trends have surfaced: The exploitation of parallelism and the design against memory latency. Into these two new trends has come the Multithreaded Virtual Processor (MVP). Based on a standard superscalar core, the MVP is able to exploit both Instruction Level Parallelism (ILP)...

  • p-type transparent electronics

    Creator:
    Valencia, Melinda Marie
    Abstract:
    The objective of this thesis is to contribute to the development of p-type materials for transparent electronics applications. Thin films of ®-BaCu2S2, a p-type semi-transparent semiconductor, are fabricated and characterized. ®-BaCu2S2 has a transmittance of 60% to 80 % in the visible portion of the electromagnetic spectrum. The mobility, conductivity,...

  • A P-well GaAs MESFET technology

    Creator:
    Canfield, Philip C.
    Abstract:
    The semiconductor gallium arsenide (GaAs) has many potential advantages over the more widely used semiconductor silicon (Si). These include higher low field mobility, semi-insulating substrates, a direct band-gap, and greater radiation hardness. All these advantages offer distinct opportunities for implementation of new circuit functions or extension of the operating conditions...

  • Recombination and generation lifetime characterization of p/p⁺ epitaxial silicon wafers

    Creator:
    Aminzadeh, Mehran G.
    Abstract:
    The refresh times of all dynamic charge storage devices, best characterized by the generation lifetime at roan temperature and the recombination lifetime at higher device operating temperatures (T>70°C), strongly influence the efficient and successful operation of dynamic charge storage devices such as DRAM's and CCD's. Both recombination and generation lifetime...

  • Modeling and development of p-type thin-film transistors

    Creator:
    Spiegelberg, Matthew Craig
    Abstract:
    The primary focus of this thesis involves modeling and development of p-type thin-film transistors (p-TFTs), moving towards the realization of a filly transparent thin-film transistor (TTFT). The modeling portion of this thesis emphasizes the development of physics-based TFT models, specifically focusing on the elucidation of non-ideal current-voltage characteristic behavior. A...

  • Drain current transient characterization of P-channel GaAs MESFET

    Creator:
    Peng, Lan L.
    Abstract:
    GaAs MESFETs are widely used in high speed integrated circuits (ICs) and microwave circuits. Due to the materials and processing methods used in GaAs MESFET fabrication, deep level traps in the substrate materials have a strong influence on device performance. In this work we used the drain current transient characterization...
