  • Adaptive model reference control of highly maneuverable high performance aircraft

    Creator:
    Collins, David C. (David Charles), 1969-
    Abstract:
    This thesis presents an adaptive model reference controller for a highly maneuverable high performance aircraft, in particular, a modified F18. An adaptive controller is developed to maneuver an aircraft at a high angle of attack. Thus, the aircraft is required to fly over a highly nonlinear flight regime. The adaptive...

  • Modeling of subthreshold current of GaAs MESFET and the design of voltage reference circuit

    Creator:
    Or, Pee-Keong
    Abstract:
    The characteristic of the subthreshold current in a GaAs MESFET exhibits a negative exponential function with Vgs. After studying the behavior of this current in this region over a range of temperature and drain bias voltages, a subthreshold current model was developed. The model was implemented in a circuit simulation...

  • A study of the temperature dependence of the DC current-voltage characteristics of AlGaAs/GaAs heterojunction bipolar transistors with application to bandgap voltage reference sources

    Creator:
    Gazeley, William G.
    Abstract:
    The bandgap voltage reference technique, as implemented in Silicon technology, has evolved to a state of advanced development and become the method of choice for temperature independent voltage biasing in integrated circuits. The heterojunction bipolar transistor (HBT), fabricated from epitaxial A1GaAs /GaAs, is developing to a point where basic circuit...

  • Design and simulation of a DC-to-DC high-frequency series-resonant converter

    Creator:
    Yazdani-Buicki, Kiyandokht
    Abstract:
    A DC-to-DC power converter was designed on the basis of pulse-area modulation which is applied to a series-resonant circuit with internal frequency of 10 Khz The series-resonant circuit was placed directly in the energy path which provides a means for the thyristors to be naturally commutated. The design was tested...

  • Synchronization in a CMOS technology

    Creator:
    Flannagan, Stephen T.
    Abstract:
    The problem of synchronization arises in the interaction among digital systems not sharing a common clock reference. The reliability of synchronizers is related to metastable operation of bistable elements. Because of its subtle nature, the phenomenon until recently was not widely researched. However, the literature now contains a sound theoretical...

  • Motion-based MPEG video summarization

    Creator:
    Colle, Olivier
    Abstract:
    A new, fully automated summarization algorithm of MPEG compressed videos is designed to address the challenge of content based video retrieval. This algorithm segments the MPEG stream motion vector magnitudes using a seed growing region technique. Following the spatial segmentation of each frame, an intra-frame class-merging operation is performed. The...

  • Cursive script recognition using a dynamic time warping method

    Creator:
    Koehler, Loren M.
    Abstract:
    This thesis is concerned with the problem of achieving accurate recognition rates for Cursive Script Recognition (CSR). Cursive Script Recognition is difficult due to writer variations such as script formation and time non-linearities. This research entailed analysis and implementation of a Cursive Script word-level Recognition system using Dynamic Time Warping...

  • 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...

  • Error canceling low voltage SAR-ADC

    Creator:
    Wen, Jianping
    Abstract:
    The design of a switched capacitor successive approximation A/D converter is discussed in this thesis. This design adopts a novel capacitance mismatch error cancellation algorithm proposed in references [25, 27]. Detailed charge domain analysis is given in this thesis, which results in an improvement of the proposed algorithm by tracing...

  • Current-mode flash analog-to-digital converter

    Creator:
    Maleki, Mohammad
    Abstract:
    This thesis describes the development of a flash analog-to-digital converter based on current-mode technique. The advantages of current -mode technique are higher speed, smaller chip area, and simple division of reference current based on current mirror. A current-mode comparator is designed consisting of a cascode current mirror and a current...
