  • A test fixture and deembedding procedure for high-frequency substrate characterization

    Creator:
    Webb, Kyle M.
    Abstract:
    At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...

  • 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...

  • Design techniques for radiation hardened-phase locked loops

    Creator:
    Nemmani, Anantha Nag
    Abstract:
    Spacecrafts experience radiation in the course of their operation and all electronic equipment on board these spacecrafts has to be designed to withstand the effects of this radiation. This thesis describes the effects of total ionization dose (TID) and single event transients (SET) in phase-locked loops - an important circuit...

  • Oscillators and phase locked loops for space radiation environments

    Creator:
    Vandepas, Martin
    Abstract:
    Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...

  • A MOSCAP pipeline pseudo passive DAC

    Creator:
    Behera, Prachee Shree
    Abstract:
    The design of a 10-bit pipelined charge redistribution DAC employing MOSCAPs biased in their accumulation mode is presented in this thesis. A switched capacitor filter and output buffer have also been designed for the system. The effect of MOSCAP nonlinearity on the performance of the pipelined charge redistribution DAC has...

  • A stochastic time-to-digital converter for digital phase-locked loops

    Creator:
    Ok, Kerem
    Abstract:
    Digital phase-locked loops (PLLs) have been receiving increasing attention recently due to their ease of integration, scalability and performance comparable to their analog counterparts. In digital PLLs, increased resolution in time-to-digital conversion is desirable for improved noise performance. This work describes the design and simulation of a stochastic time-to-digital converter...

  • Garbage in, garbage out? An empirical look at oracle mistakes by end-user programmers

    Creator:
    Phalgune, Amit
    Abstract:
    End-user programmers, because they are human, make mistakes. However, past research has not considered how visual end-user debugging devices could be designed to ameliorate the effects of mistakes. This paper empirically examines oracle mistakes mistakes users make about which values are right and which are wrong to reveal differences in...

  • End user software engineering features for both genders

    Creator:
    Sorte, Shraddha
    Abstract:
    Previous research has revealed gender differences that impact females’ willingness to adopt software features in end users’ programming environments. Since these features have separately been shown to help end users problem solve, it is important to female end users’ productivity that we find ways to make these features more acceptable...

  • Planning in multi-agent partially observable domains using sparse sampling

    Creator:
    Donneau-Golencer, Thierry D.
    Abstract:
    A large number of sequential decision-making problems in uncertain environments can be modeled as Markov Decision Processes (MDPs). In such settings, an agent can observe at each time step the state of the environment and then executes an action, causing a stochastic transition to a new state of the environment...

  • Implementation of an ultra-wideband transceiver for sensor applications

    Creator:
    Jann, Benjamin J.
    Abstract:
    Ultra-wideband (UWB) radio is the transmission of data using an extremely wide bandwidth and very low power spectral density. In this thesis, the mereits and challenges of UWB architectures versus conventional narrowband architectures will be compared. Pulsed UWB systems can be implemented with very simple architectures. These advantages make UWB...
