  • A practical implementation of self-efficacy theory to improve the engineering curriculum

    Creator:
    Plisch, Marjorie
    Abstract:
    What are the most effective ways to improve the engineering curriculum? Improvements should result in increased student retention, undergraduates who are more industry-ready and graduates who are better prepared to be leaders. Current research suggests that the best predictor of persistence is a person’s self-efficacy. The focus of this thesis...

  • Design techniques for PVT tolerant phase-locked loops

    Creator:
    Wu, Ting
    Abstract:
    The continued scaling of deep-submicron CMOS technology enables low-voltage high-frequency phase-locked loops (PLLs) to be fully integrated in complex mixed-signal systems. However, fluctuations due to the manufacturing process and variations in environmental conditions, such as supply voltage and temperature, are also significantly increased. As a result, the performance of PLLs...

  • Investigation and comparison of generators for dynamic operation in ocean buoys

    Creator:
    Schacher, Anthony Clinton
    Abstract:
    A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...

  • Low noise clocking for high speed serial links

    Creator:
    Brownlee, Merrick
    Abstract:
    As the functionality of digital chips continues to increase dramatically, chip- to-chip communication bandwidths must scale accordingly to avoid constraining the overall system performance. Therefore, high speed transceiver design has be- come an important research topic. In particular, the performance of the circuits that are responsible for timing accuracy are...

  • Low voltage techniques for pipelined analog-to-digital converters

    Creator:
    Carnes, Joshua Kenneth
    Abstract:
    To realize pipelined ADCs in deep-submicron processes, low voltage techniques must be developed to work around problems created by limited supply voltages such as the floating switch dead zone, reduced SNR, and reduced OpAmp performance. This thesis analyzes standard and low voltage design issues for pipelined ADCs and proposes a...

  • Influence of adjustable speed drive on induction motor fault detection using stator current monitoring.

    Creator:
    Al-Shahrani, Ali
    Abstract:
    The detection of motor faults at their incipient stage is of prime importance to any industrial plant. The introduction of adjustable speed drives has improved the control and the efficiency of induction motors, however, this has changed the nature of motor faults and how they can be detected. Current signature...

  • Efficient power conversion interface circuits for energy harvesting applications

    Creator:
    Le, Triet T.
    Abstract:
    Harvesting energy from the environment for powering micro-power devices have been increasing in popularity. These types of devices can be used in embedded applications or in sensor networks where battery replacement is impractical. In this dissertation, different methods of energy harvesting from the environment are explored as alternative sources of...
