  • A 10 bit algorithmic A/D converter for a biosensor

    Creator:
    Rengachari, Thirumalai
    Abstract:
    This thesis presents a novel algorithmic A/D converter to be used in a biosensor. The converter is capable of a conversion rate of 1.5 bits/phase and hence the required conversion time is reduced. The proposed architecture is analyzed for non-ideal effects and compared with existing algorithmic A/D architectures. The converter...

  • Enhanced inverse synthetic aperture radar imagery using 2-D spectral estimation

    Creator:
    Ohm, David R.
    Abstract:
    This research focused on the use of classical and modern two-dimensional spectral estimation techniques for enhancing inverse synthetic aperture radar (ISAR) imagery. 2-D Classical spectral estimation methods and 2-D modern parametric and non-parametric spectral estimation methods are applied to simulated and real data sets in order to achieve both range...

  • Design of a 14-bit continuous-time Delta-Sigma A/D modulator with 2.5MHz signal bandwidth

    Creator:
    Li, Zhimin
    Abstract:
    In recent years, there has been growing interest in both industry and academia to use continuous-time (CT) Δ-Σ A/D converters for wideband wireless and wireline communication applications. So far no reported CT Δ-Σ A/D modulator achieves 14-bit or higher dynamic range (DR) with more than 2MHz signal bandwidth (equivalently 4MS/s)....

  • Metal fill considerations for on-chip interconnects and spiral inductors

    Creator:
    Shilimkar, Vikas S.
    Abstract:
    Variability in circuit performance due to process defects is a major concern in integrated circuit (IC) fabrication. Advanced IC manufacturing processes employ Chemical-Mechanical Polishing (CMP) for planarization of oxide and metal layers. CMP defects result in variations in the oxide and metal topographical profile. To reduce these topographical variations, electrically...

  • Al-In-Sn-O thin-film transistors

    Creator:
    Stewart, Kevin A.
    Abstract:
    The aim of the research undertaken for this thesis was to develop a new high-performance amorphous oxide semiconductor (AOS) for use as a channel layer in a thin-film transistor (TFT). AOS TFTs offer higher electron mobility than the established amorphous silicon based technology. A new channel material comprised of aluminum...

  • Structured representation of composite software changes

    Creator:
    Chabra, Aarti
    Abstract:
    In a software development cycle, programs go through many iterations. Identifying and understanding program changes is a tedious but necessary task for programmers, especially when software is developed in a collaborative environment. Existing tools used by the programmers either lack in finding the structural differences, or report the differences as...

  • Ultra-wideband indoor localization systems

    Creator:
    Ye, Ruiqing
    Abstract:
    Indoor localization systems have a variety of applications such as tracking of assets, indoor robot navigation, and monitoring of people (e.g. patients) in hospitals or at home. Global positioning system (GPS) offers location accuracy of several meters and is mainly used for outdoor location-based applications as its accuracy degrades significantly...
