  • Analysis and design on low-power multi-Gb/s serial links

    Creator:
    Hu, Kangmin
    Abstract:
    High speed serial links are critical components for addressing the growing demand for I/O bandwidth in next-generation computing applications, such as many-core systems, backplane and optical data communications. Due to continued process scaling and circuit innovations, today's CMOS serial link transceivers can achieve tens of Gb/s per pin. However, most...

  • Offloading of I/O transactions in current CPU architectures

    Creator:
    Larsen, Steen K.
    Abstract:
    IO transactions within a computer system have evolved along with other system components (i.e., CPU, memory, video) from programmed IO (PIO). In current mainstream systems (spanning from HPC to mobile) the IO transactions are CPU-centric descriptor-based DMA transactions. The key benefit is that slower IO devices can DMA write system...

  • Model-based solution techniques for the source localization problem in distributed parameter systems

    Creator:
    Alpay, Mehmet Emin
    Abstract:
    In this thesis, three model-based methods are presented for finding the location of a point source with possibly time-varying strength for a class of distributed parameter systems. The first method involves off-line numerical computation of the time-response data at the sensor(s) from all possible source locations and functions of source...

  • Sensor Interface Circuit Design towards CMOS Scaling

    Creator:
    Liu, Jialin
    Abstract:
    Sensor system plays an important role in connecting everything including human body to the electrical information systems that we have built and that we are going to build, to make the world more intelligent and efficient. One of the key propulsive forces behind these emerging techniques is CMOS scaling that...

  • Sizing and Performance of the Pendulum Power Take-Off Wave Energy Converter: Modularity and Chaotic Behavior

    Creator:
    Dizon, Chris
    Abstract:
    Multiple wave energy converter (WEC) archetypes exist with varying power take-off (PTO) designs in the attempt to maximize ocean energy harnessed and converted into useful energy. The pendulum PTO is popular for its simple, yet robust functionality due to its internally located components and simple operation. Additionally, this PTO does...

  • Ultra-energy-efficient Silicon Photonic Modulators Driven by Transparent Conductive Oxides

    Creator:
    Li, Erwen
    Abstract:
    Silicon photonics has become the most promising platform for future large-scale optical interconnect and optical computing systems due to its inherent CMOS compatibility, which brings exclusive advantages in bandwidth density, energy efficiency, and cost effectiveness. Parallel optical interconnects based on photonic integrated circuits (PICs) have the capacity to meet the...

  • Advanced microarchitecture and circuit design techniques for on-chip memories in CMOS technology

    Creator:
    Hsu, Steven K.
    Abstract:
    In modern on-chip memories, an increasing demand for higher performance, lower power, reduced area, and improved robustness creates a rising need for advanced microarchitecture and circuit design techniques. Particularly in large-signal multi-ported register files, these advanced design techniques include: (i) multi-banked arrays, (ii) multi-frequency arrays, (iii) multi-bit width gating, (iv)...

  • Novel power conditioning circuits for piezoelectric micro power generators

    Creator:
    Han, Jifeng
    Abstract:
    Advanced low power devices promote the development of micro power generators (MPGs) to replace the batteries to power them. Due to the trend in decreasing integrated circuit (IC) supply voltages, power supply designers are facing more and more serious challenges. The objective of this research is to design a power...

  • Global Hierarchical Control of a Park of Spar Buoy-type Floating Oscillating Water Column Wave Energy Converters

    Creator:
    Gaebele, Daniel T.
    Abstract:
    Converting energy from ocean waves is a challenging area for control theory application because of the nonlinear dynamics in various time scales. Generally, wave energy converter (WEC) control is applied in order to maximize power absorption, in the most common wave conditions, and subject to the devices’ physical constraints. Commonly,...

  • Analysis of subsynchronous resonance in power systems

    Creator:
    Zhu, Wenchun
    Abstract:
    Three aspects of Subsynchronous Resonance (SSR) related problems in power systems are addressed in this dissertation which aims at contributing to a better understanding of these problems. Subsynchronous Resonance (SSR) problems in series compensated steam-turbine power systems co-exist with the beneficial effects provided by the series capacitors. Since the early...
