  • The architecture and design of a parallel sorting engine

    Creator:
    Bate, John G.
    Abstract:
    Sorting is typically a compute intensive operation used in many areas of industry. With improved technology, both in the VLSI and CAE areas, we can afford to develop hardware based database computers to move the work load off the main computer. In this thesis the architecture of a VLSI parallel...

  • Equivalent circuit modeling of on-chip magnetic devices based on terminal measurements

    Creator:
    Gaskill, Steven G.
    Abstract:
    The addition of thin-film alloy magnetic materials to integrated circuit processing enables a number of novel monolithic circuits. Examples include fully integrated magnetic field sensors, signal and power galvanic isolation circuits, and power supplies on chip (PwrSoC). There are several benefits to integrating these traditionally off-chip devices, including improved manufacturability,...

  • Timing jitter and phase noise in electronic oscillators

    Creator:
    Zhang, Chengwei
    Abstract:
    In the first part of this dissertation, low frequency l/f or flicker noise in the frequency range of Hz to kHz has been identified and demonstrated to be described by temperature fluctuations in heat conduction in bipolar transistors operated at higher power densities. This noise phenomenon is not described by...

  • Determination of magnetoelastic parameters in magnetic thin films from FMR spectra

    Creator:
    Masood, Khalid I.
    Abstract:
    The ferromagnetic resonance (FMR) phenomenon serves as a sensitive probe of the effective internal fields in a magnetic material. FMR spectroscopy has consequently become a well-established technique, extensively employed in assessing material properties such as magnetic anisotropy, Landé g-factor, damping parameter, and the magnetoelastic constants of magnetic materials. Determining these...

  • Power-Efficient Design Techniques and Architectures for Scalable Submicron Analog Circuits

    Creator:
    Xu, Yang
    Abstract:
    As the CMOS process scales down to submicron, digital circuit performance improves, while reduced supply voltage and lower transistor intrinsic gain make it difficult to implement analog circuits in a power efficient manner. Therefore, it has become advantageous to shift more analog signal processing functions conventionally realized in voltage (analog)...

  • Wideband and high accuracy delta sigma modulation data converter

    Creator:
    Jung, Youngho
    Abstract:
    Nowadays, needs for wideband and high accuracy analog-to-digital converter are increasing rapidly in manifold applications such as wireless communication, digital video and other consumer electronics. Besides, low power consumption is required to have longer battery life in portable systems. CMOS technology scaling and innovative modulator topology make the implementation much...

  • Design techniques for low power ADCs

    Creator:
    Yu, Wenhuan
    Abstract:
    This dissertation presents an incremental analog-to-digital converter (ADC) with digital digital-to-analog converter (DAC) mismatch correction. A theoretical time-domain analysis technique was developed to predict the noise performance of the incremental ADC, and a new optimization technique was proposed to minimize the output noise. In the calibration mode, the incremental ADC...

  • Electric Machine Capability Characterization for Actuators in Disaster Response Robots

    Creator:
    Li, Qianyun
    Abstract:
    Disaster response robots need to be simultaneously able to survive extreme environment and complete the mission efficiently and robustly. One of the determinants is the performance of the actuators in each joint, which drive the robot to the desired motion accurately. In robotics society, people usually build their robots directly...

  • A VHDL description of speech recognition front-end

    Creator:
    Xiao, Xin
    Abstract:
    This thesis investigates an implementation of speech recognition front-end. It is an application specific integrated circuit (ASIC) solution. A Mel Cepstrum algorithm is implemented for the feature extraction. We present a new mixed split-radix and radix-2 Fast Fourier Transform (FFT) algorithm, which can effectively minimize the number of complex multiplications...

  • The analysis and synthesis of a parallel sorting engine

    Creator:
    Ahn, Byoungchul
    Abstract:
    This thesis is concerned with the development of a unique parallel sort-merge system suitable for implementation in VLSI. Two new sorting subsystems, a high performance VLSI sorter and a four-way merger, were also realized during the development process. In addition, the analysis of several existing parallel sorting architectures and algorithms...
