  • Single-level dynamic register caching architecture for high-performance superscalar processors

    Creator:
    Liebert, John A.
    Abstract:
    The amount of instruction level parallelism (ILP) that can be exploited depends greatly on the size of the instruction window and the number of in-flight instructions the processor can support. However, this requires a register file with a large set of physical registers for renaming and multiple ports to provide...

  • Generalized radix design techniques for low-power, low voltage pipelined and cyclic analog-digital converters

    Creator:
    Sharma, Vivek
    Abstract:
    This thesis proposes a novel technique for the design of pipelined and cyclic ADCs utilizing generalized radix gain stages. Several models have been proposed for the optimization of high performance pipelined ADCs by various researchers. This work builds upon them, using a simple but accurate model to estimate the optimal...

  • Side channel attack resistant elliptic curves cryptosystem on multi-cores for power efficiency

    Creator:
    Yoo, Jaewon
    Abstract:
    The Advent of multi-cores allows programs to be executed much faster than before. Cryptoalgorithms use long-bit words thus parallelizing these operations on multi-cores will achieve significant performance improvement. However, not all long-bit word operations in cryptosystems are suitable for parallel execution on multi-cores. In particular, long-bit words used in Elliptic...

  • Some contributions to asymmetric error control codes

    Creator:
    Elmougy, Samir
    Abstract:
    In some practical systems, most of the errors are of 1 → 0 type and 0 → 1 errors occur very rarely. In this thesis, first, the capacity of the asymmetric channel is derived. The capacity of the binary symmetric channel (BSC) and the Z-channel can be derived from this...

  • An ultra low voltage micropower GPS receiver RF front-end for wildlife tracking

    Creator:
    Heiberg, Adam C.
    Abstract:
    A fully integrated CMOS GPS receiver RF front end optimized for low power operation is presented. The system operates with a supply voltage down to 250 mV. A prototype has been fabricated in a 0.13μm CMOS process and includes a low voltage LNA, quadrature oscillators, and quadrature mixers. It exhibits...

  • A study of basic building blocks of analog-to-digital delta-sigma modulators

    Creator:
    Guo, Yuhua
    Abstract:
    In this thesis, a novel Direct-Charge-Transfer (DCT) integrator structure is proposed, which can settle much faster than regular switch-capacitor integrators. A new Spread-Spectrum Dynamic Element Matching (SS-DEM) algorithm is also introduced, which can effectively spread or shape the nonlinearity error of multi-bit DAC in the feedback path, thus improve the...

  • 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...

  • High-performance delta-sigma analog-to-digital converters

    Creator:
    da Silva, Jose Barreiro
    Abstract:
    Multi-stage delta-sigma (ΔΣ) architectures, commonly known as MASH, are the preferred choice for analog-to-digital converters (ADCs) used in broadband communication applications, where high-resolution (above 14 bits) and high-bandwidth (several MHz) performances are required. Current state-of-the-art designs are capable of as much as 5-MS/s output data rates with 90-dB SNR. However,...

  • Growth and characterization of zinc ferrite thin films for high frequency applications

    Creator:
    Hu, Jiqing
    Abstract:
    Ferrites have been used for various high frequency applications as bulk materials. These applications, however, are limited to large dimension devices. In this thesis, thin film ferrites were deposited from a low temperature solution-based deposition process that is suitable for micro-scale high frequency applications. The low temperature nature of this...

    Creator:
    Chang, Yuhao
    Abstract:
    This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...
