  • Prototyping of Thermoelectric Energy Harvesting Circuitry for IoT Devices

    Creator:
    Webb, Derek
    Abstract:
    Due to the advancement of incredibly low power microcontrollers and small form factor integrated circuits, energy harvesting can be considered as an alternative, low power source for remote ocean sensing and measurements. To demonstrate the effectiveness of harvesting thermoelectric energy contained in the temperature differential between ocean surface water and...

  • Multi-Objective Power Electronics System Design and Optimization, A Machine Learning Approach

    Creator:
    Jackson, Derek
    Abstract:
    The integration of power electronics within the energy and transportation sectors enlists a demand for the rapid development of energy-efficient electrical systems. While model-based design and physics-based simulations are effective ways to handle the multi-disciplinary and multi-objective (MO) design of these complex systems, design exploration remains a time-consuming procedure. A...

  • Development of zinc tin oxide-based transparent thin-film transistors

    Creator:
    Chiang, Hai Q.
    Abstract:
    The focus of this thesis involves development of highly transparent, n-channel, accumulation- mode thin-film transistors employing a zinc tin oxide (ZTO) channel layer. ZTO-based transparent thin-film transistors (TTFTs) show improved device performance compared to ZnO-based TTFTs. An estimated peak effective mobility for these devices as high as ~100 cm² V⁻¹sec⁻¹...

  • Network monitoring with focus on HTTP

    Creator:
    Schmid, Andreas
    Abstract:
    Since its introduction in the early 1990s, the quick growth of the World Wide Web (WWW) traffic raises the question of whether past Local Area Network (LAN) packet traces still reflect the current situation or whether they have become obsolete. For this thesis, several LAN packet traces were obtained by...

  • Tone burst deconvolution

    Creator:
    Rathja, Roy C.
    Abstract:
    The suitability of discrete least-squares optimal (Wiener) filters for deconvolution of tone-burst waveforms is studied. It is shown that: (1) such waveforms are not well suited to these filters without preprocessing, (2) the use of exponential weighting results in a significant improvement in filter performance and (3) that "phase-unwrapping" in...

  • Design techniques for successive approximation register analog-to-digital converters

    Creator:
    Tong, Tao
    Abstract:
    Successive approximation register analog-to-digital converters (SAR ADCs) have been widely used for medium-speed, medium-resolution applications due to their excellent power efficiency and digital compatibility. Recently, SAR ADCs are also penetrating into the applications which have been earlier dominated by delta-sigma ADCs and pipeline ADCs. However, the resolution of SAR ADCs...

  • Frequency domain deconvolution

    Creator:
    Tan, Hin Leong
    Abstract:
    Frequency domain design of deconvolution filters is studied using Fast Fourier Transform. Filters for both the spike and the Gaussian reflector wavelet are obtained. True deconvolution filters are infinitely long IIR filters, and frequency domain analysis is an effective way of finding its optimum finite length approximation for an arbitary...

  • Linearizing techniques for voltage controlled oscillator based analog to digital converters

    Creator:
    Rao, Sachin B.
    Abstract:
    Voltage controlled oscillator (VCO) based ADC is an important class of time-domain ADC that has gained widespread acceptance due to their several desirable properties. VCO-based ADCs behave like an open-loop continuous time ΔΣ modulator and achieve excellent resolution by first order noise shaping the quantization error. However, the SNDR of...

  • Compressive Sensing for Low Power Sensor Design

    Creator:
    Behravan, Vahid
    Abstract:
    Recent sensor System-on-Chips (SoC) have enabled significant advances in energy-efficiency by incorporating various micro-powered building blocks. Unfortunately, most of these sensor systems do not address the high power cost associated with data storage and transmission, which in some cases vastly exceeds the power consumed by the rest of the SoC....
