  • An ultra low power frequency reference for timekeeping applications

    Creator:
    Oporta, Hector Ivan
    Abstract:
    An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A subthreshold voltage regulator provides a supply voltage for the oscillator with minimum current consumption. The oscillator and regulator...

  • A resource-constrained scheduling scheme that considers resources operating at multiple voltages and register assignment

    Creator:
    Lee, Chee
    Abstract:
    Power and timing requirements are becoming more and more stringent as applications move from less mobile devices to more mobile ones. As such, it is important to optimize these applications as much as possible in order to provide the best solution that is low power and low latency. Although there...

  • Optimizing performance/watt of embedded SIMD multiprocessors through a priori application guided power scheduling

    Creator:
    Albright, Ryan K.
    Abstract:
    A method for improving performance/watt of an embedded single-instruction multiple-data (SIMD) architecture using application-guided a priori scheduling of hardware resources is presented. A multi-core architectural simulator is adopted that accurately estimates power, performance, and utilization of various processor components (logic, interconnect and memory). A greedy search is then performed on...

  • Low power scheduling schemes that consider latency and resource constraints at multiple voltages

    Creator:
    Huang, Shyh-Sen
    Abstract:
    Power reduction can be achieved at many different levels, such as architecture, algorithm, logic, and transistor levels in circuit design. This thesis focuses on low power scheduling at the algorithm level. We present a latency-constrained scheduling and a latency and resource constrained scheduling, which minimize power consumption for the resources...

  • High-performance low-power microprocessor circuits

    Creator:
    Hsu, Steven K.
    Abstract:
    This thesis will discuss two critical components of a digital system -- domino logic styles and flip-flops. In today's microprocessors, both domino logic and flip-flops are essential to high-performance and low-power design. Two new domino logic styles are presented and analyzed, Double Edge Triggered (DET) and Double Data Rate (DDR)...

    Creator:
    Farahbakhshian, Farhad
    Abstract:
    An enhanced swing differential Colpitts VCO (ESDC-VCO) dramatically improves the swing of a Colpitts VCO by allowing the signal to swing below ground and above the supply voltage. Fabricated in a 1P8M 0.13 um CMOS process, the ESDC-VCO operates at 4.9GHz with a 0.475-V supply and consumes 2.7mW. The measured...
