  • Low power, high performance pseudo-static D flip-flop

    Creator:
    Low, Tim D.
    Abstract:
    Digital systems, in particular microprocessor, have recently experienced phenomena growth in performance. Both technology advancement and clever design have sustained this performance growth. As clock frequency heads into the Ghz range, new circuit design, for both logic and storage, are needed. Such new circuit technology must provide needed performance with...

  • Drain current transient characterization of P-channel GaAs MESFET

    Creator:
    Peng, Lan L.
    Abstract:
    GaAs MESFETs are widely used in high speed integrated circuits (ICs) and microwave circuits. Due to the materials and processing methods used in GaAs MESFET fabrication, deep level traps in the substrate materials have a strong influence on device performance. In this work we used the drain current transient characterization...

  • Silencer! : a tool for substrate noise coupling analysis

    Creator:
    Birrer, Patrick
    Abstract:
    This thesis presents Silencer!, a fully automated, schematic-driven tool for substrate noise coupling simulation and analysis. It has been integrated in the CADENCE DFII environment and seamlessly enables substrate coupling analysis in a standard mixed-signal design flow. Silencer! aids IC designers in the analysis of substrate noise coupling at different...

  • Analysis and modeling of substrate noise coupling for NMOS transistors in heavily doped substrates

    Creator:
    Hsu, Shu-ching
    Abstract:
    This thesis examines substrate noise coupling for NMOS transistors in heavily doped substrates. The study begins with the analysis of an NMOS transistor switching noise in a digital inverter at the device level. A resistive substrate network for the NMOS transistor is proposed and verified. Coupling between N+- P+ contacts...

  • LORAN-C receiver position estimation from noisy time-difference data

    Creator:
    Weisshaar, Andreas
    Abstract:
    In order to analyze the accuracy of the navigation system LORAN-C, we have collected time - difference (TD) data from the U.S. west coast chain (9940) at a fixed receiver location (Corvallis, Oregon). The analysis of the TD data shows an unexpected high correlation between the TDs as well as...

  • Proposed implementation of a near-far resistant multiuser detector without matrix inversion using Delta-Sigma modulation

    Creator:
    Myers, Timothy F.
    Abstract:
    A new algorithm is proposed which provides a sub-optimum near-far resistant pattern for correlation with a known signal in a spread-spectrum multiple access environment with additive white gaussian noise (AWGN). Only the patterns and respective delays of the K-1 interfering users are required. The technique does not require the inversion...

  • Network coding for sensor networks, distributed storage and video streaming

    Creator:
    Nguyen, Kien Trung
    Abstract:
    The classical store-and-forward routing has and will continue to be the most important routing architecture in many modern packet-switched communication networks. In a packet-switched network, data is sent in the form of discrete packets that traverse hop-by-hop from a source to a destination. At each intermediate hop, the router stores...

  • Amorphous oxide semiconductors in circuit applications

    Creator:
    McFarlane, Brian Ross
    Abstract:
    The focus of this thesis is the investigation of thin-film transistors (TFTs) based on amorphous oxide semiconductors (AOSs) in two circuit applications. To date, circuits implemented with AOS-based TFTs have been primarily enhancement-enhancement inverters, ring oscillators based on these inverters operating at peak frequencies up to ~400 kHz, and two-transistor...

  • Energy Harvesting and Power Management Integrated Circuits for Self-Sustaining Wearables

    Creator:
    Bose, Soumya
    Abstract:
    Harvesting energy from ambient sources can provide power autonomy to energy efficient electronics and sensors. The last decade has seen a multitude of ways to scavenge energy from various sources like solar, thermal, electromagnetic, electrostatic, piezo-electric and many more. Thermal energy from human body heat is ubiquitous and can be...

  • Comparison of time-domain and frequency-domain phase noise analyses

    Creator:
    Vytyaz, Igor
    Abstract:
    This thesis presents a comparison of time-domain and frequency-domain algorithms for phase noise calculation in oscillators. Floquet theory provides the mathematical foundation for these calculations and the numerical methods employ perturbation projection vectors (PPVs). The PPVs are an estimate of an oscillator's sensitivity to noise. The in-house circuit simulator SPICE3...
