  • Scaled modeling and simulation of ocean wave linear generator buoy systems

    Creator:
    Gore, Ganesh P.
    Abstract:
    Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...

  • 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...

  • Modified VLSI designs for error correction codes

    Creator:
    Chen, Lupin
    Abstract:
    Nowadays, error correction codes have become an integral part in almost all the modern digital communication and storage systems. With the continuously increasing demands for higher speed and lower power communication systems, efficient VLSI implementations of those error correction codes have great importance for practical applications. In this thesis, several...

  • A channelized digital receiver design for UWB sytems in a multipath indoor environment

    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...

  • A survey on continuous-time modulators : theory, designs and implementations

    Creator:
    Gao, Xiaoran
    Abstract:
    Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...

  • A dual-path 2-0 MASH ADC with dual digital error correction

    Creator:
    Zhang, Zhenyong
    Abstract:
    This dissertation presents a dual-path 2-0 MASH (Multi-stAge-noise -SHaping) ADC with two verified digital corrections of DAC mismatch error and quantization noise leakage. By using these two techniques, the requirements for the analog circuits are greatly relaxed. The dual-path structure generates two outputs, one only composed of conversion errors, the...

  • A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

    Creator:
    Fang, Jie
    Abstract:
    Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

  • Low-voltage data converters

    Creator:
    Meng, Qingdong
    Abstract:
    With the growing demand for portable/consumer electronics, such as digital audio/video (AV), the downscaling of device dimensions, which enables the integration of an increasing number of transistors in a single chip, is mandatory. This trend also continuously pushes the power supply voltage down to reduce the power consumption and improve...

  • Design techniques for low-voltage and low-power analog-to-digital converters

    Creator:
    Ahn, Gil Cho
    Abstract:
    With the ever-increasing demand for portable devices used in applications such as wireless communication, mobile computing, consumer electronics, etc., the scaling of the CMOS process to deep submicron dimensions becomes more important to achieve low-cost, low-power and high-performance digital systems. However, this downscaling also requires similar shrinking of the supply...

    Creator:
    Brown, Matthew Eugene
    Abstract:
    There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...
