  • Low-power design techniques for low-voltage analog-to-digital converters

    Creator:
    Kim, Min Gyu
    Abstract:
    The demand for portable electronic systems and the continued down-scaling of device dimensions resulted in rapid improvement in the performance of integrated systems. Several low-voltage design techniques have been proposed to operate analog circuits with sub-1V supply. However, these techniques require higher power consumption to achieve large dynamic range while...

  • International students as educational migrants : east and southwest Asian perspectives

    Creator:
    Visconti, Lauren A.
    Abstract:
    Projected to reach one million people next year, international students in the United States are undergoing a transformative educational migration. Moving away from the existing study abroad paradigm is the first step to more accurately understand the lived experience of an educational migrant. Discovering the perceptions of what value an...

  • Terahertz transmission & spectroscopy of vertically grown multi-walled carbon nanotube forests

    Creator:
    Maizy, Louis
    Abstract:
    In this thesis, I present studies in the field of terahertz [THz] spectroscopy. It covers both the generation and detection of ultra-fast broadband THz pulses, as well as the transmission properties of vertically grown multi-walled carbon nanotube forests [MWCNTs]. We have found that these vertically grown MWCNTs respond strongly to...

  • Nonlinear Terahertz Spectroscopy and imaging of Carbon Nanomaterials

    Creator:
    Lee, Byounghwak
    Abstract:
    This dissertation presents nonlinear terahertz (THz) properties of carbon nanomaterials investigated by time-resolved high-field THz spectroscopy. In order to determine THz characteristics of nanomaterials, we performed THz power spectrum measurement, THz raster imaging, THz time-domain spectroscopy (THz-TDS) and time-resolved pump-probe experiment on two different types of single layer graphene and...

  • Design techniques for clocking high performance signaling systems

    Creator:
    Hanumolu, Pavan Kumar
    Abstract:
    Scaling of CMOS technology has progressed relentlessly for the past several decades. In order for this unprecedented scaling to benefit the performance of large digital systems, the communication bandwidth between integrated circuits (ICs) must scale accordingly. However, interconnect technology does not scale as aggressively, making communication between chips the major...

  • LPBF and Post Processing of H13 Tool Steel

    Creator:
    Alabdulali, Ali
    Abstract:
    Laser powder bed fusion (LPBF) is an innovative method where metal powder is fused together to generate complex geometries. LPBF is used as a technology to reduce material waste, and extensive labor that are often linked to conventional subtractive manufacturing. H13 tool steel is one of the widely used materials...

  • Growth, Characterization and Applications of Zinc Sulfide Thin Films by Solution-Based Processes

    Creator:
    Chiu, Dick
    Abstract:
    Zinc Sulfide (ZnS) thin film, with a wide band gap, has been used for many applications, such as buffer layer for CIGS solar cells, light emitting diodes and thin film electroluminescent devices. In this work, ZnS thin films were prepared using two different deposition processes. In the first method, ZnS...

  • 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 data converters

    Creator:
    Meng, Qingdong
    Abstract:
    With the growing demand for portable/consumer electronics, such as digital audio/video (AV), the downscaling of device dimensions, which enables the integration of an increasing number of transistors in a single chip, is mandatory. This trend also continuously pushes the power supply voltage down to reduce the power consumption and improve...

  • Terahertz Imaging and Nonlinear Spectroscopy of Semiconductors using Plasmonic Devices

    Creator:
    Thompson, Zachary James
    Abstract:
    In this dissertation, a series of studies in the field of terahertz (THz) science are presented, specifically using nonlinear THz spectroscopy. We exploit huge field enhancement and subwavelength confinement in plasmonic structures. There are three distinct projects which will be discussed: nonlinear THz spectroscopy using plasmonic induced transparency (PIT), THz-triggered...
