  • Understanding the ultra-wideband channel within a computer chassis

    Creator:
    Redfield, Stephen J.
    Abstract:
    Recent developments in computing technology have generated a demand for more streamlined and effective test systems. By replacing traditional in-chassis wired interconnects with a broadcast wireless system, fault detection and error susceptibility will drastically improve, input/output capabilities will expand, and routing complexity will decrease. Ultra-wideband impulse radio's (UWB-IR) characteristic multipath-immunity...

  • 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...

  • End-user programming tool for creating custom health surveys with automatically generated reports

    Creator:
    Krishnamurthy, Pratik
    Abstract:
    Online survey data collection is becoming popular because it provides benefits in cost, ease of collecting and managing data, flexibility in format, and access to a diverse population. Surveys are often used for health studies such as Oregon State University’s WAVE Project, which utilizes the WavePipe system, a server enabling...

  • Electrically tunable thin-film inductors based on synthetic antiferromagnet cores

    Creator:
    An, Na
    Abstract:
    The objective of this research is to demonstrate the feasibility of implementing electrically tunable on-chip inductors based on synthetic antiferromagnet (SAF) cores. This thin film magnetic core is made of a magnetic bi-layer antiferromagnetically coupled through a nonmagnetic spacer layer. An energy model is developed to investigate the magnetic behavior...

  • 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...

  • Aerodynamic undertray design for formula SAE

    Creator:
    Jensen, Karl
    Abstract:
    Aerodynamic improvements in automotive racing can have a significant effect on vehicle performance. Recent developments in Formula SAE (Society of Automotive Engineers) have included the design and implementation of aerodynamic devices such as inverted wings and undertrays to improve performance. In this work the literature of undertray technology is presented...

  • Ultra-low power receivers for wireless sensor networks

    Creator:
    Ayers, James S.
    Abstract:
    In wireless sensor network applications, low-power operation of the wireless receiver is critical. To address this need an ultra-low power Binary Frequency Shift Keying (BFSK) receiver using the super-regenerative architecture is developed. A prototype receiver is built and tested for operation in the 900 MHz ISM band. Lab measurements show...

  • Efficient decoder design for error correction codes

    Creator:
    He, Jinjin
    Abstract:
    Error correction codes (ECCs) have been widely used in communication systems and storage devices. Nowadays, the rapid development of integrated circuit technologies makes feasible the implementation of powerful ECCs such as turbo code and low-density parity-check (LDPC) code. However, these high-performance codes require complex decoding algorithms, resulting in large hardware...

  • Dynamic biasing for ring amplification

    Creator:
    Farahbakhshian, Farshad
    Abstract:
    New amplifier architectures are presented using non-traditional methods of biasing. Time-based dynamic biasing and signal-based dynamic biasing are discussed in the context of new architectures. This includes a new form of ring amplification with a dynamic deadzone, allowing for a structure whose coarse path does not consume static power.

  • Receiver synchronization for UWB TDOA localization

    Creator:
    Baek, Seungjin
    Abstract:
    Pulsed ultra-wideband (UWB) radio uses extremely short pulses to transmit information. Such pulses provide very fine timing information, which has led to technological advances in high-precision localization. This thesis investigates UWB localization strategies with a focus on receiver synchronization algorithms for time-difference-of-arrival localization to achieve centimeter accuracies in a 3-dimensional...
