  • Optimum quantization for the adaptive loops in MDFE

    Creator:
    Parthasarathy, Priya
    Abstract:
    Multi-level decision feedback equalization (MDFE) is a sampled signal processing technique for data recovery from magnetic recording channels which use the 2/3(1,7) run length limited code. The key adaptive feedback loops in MDFE are those which perform the timing recovery, gain recovery, dc offset detection, and adaptive equalization of the...

  • Comparison of DPCM and Subband Codec performance in the presence of burst errors

    Creator:
    Bhutani, Meeta
    Abstract:
    This thesis is a preliminary study of the relative performance of the major speech compression techniques, Differential Pulse Code Modulation (DPCM) and Subband Coding (SBC) in the presence of transmission distortion. The combined effect of the channel distortions and the channel codec including error correction is represented by bursts of...

  • Opamp characterization techniques

    Creator:
    Ramamurthy, Karthik
    Abstract:
    Standard methodologies exist for testing and characterizing digital circuits but the same cannot be said of analog circuits. Though much theoretical work has been done to model the linear and nonlinear aspects of analog circuits, a firm practical background for the design of testable analog cells has yet to be...

  • New Techniques for Multi-Channel Biosignal Acquisition and Low-Power, Low-Resistance-Measurement Systems

    Creator:
    Kim, Jinyong
    Abstract:
    Dense electrical recording of biosignals has been developed to provide spatial resolution and precise temporal information for health monitoring, diagnostics, and clinical research. However, more electrodes require more wires, and wiring density quickly becomes a limiting factor. To break this bottleneck, we proposed a frequency-division multiplexing (FDM) based architecture for...

  • Novel switched-capacitor circuits for delta-sigma modulators

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Oversampled delta-sigma modulation is one of the widely used A/D conversion techniques for narrow bandwidth signals. In this study several new lowpass and bandpass delta-sigma modulator architectures as well as novel pseudo-N-path integrators that can be used in implementing these architectures are proposed. By using multiplexing techniques the new lowpass...

  • Improved design techniques for low-voltage low-power switched-capacitor delta-sigma modulators

    Creator:
    Grilo, Jorge
    Abstract:
    This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of improving the performance and optimizing for low power dissipation. This is accomplished by identifying critical elements whose performance can lead to increased power dissipation,...

  • 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...

  • Space time coding in MIMO systems

    Creator:
    Xian, Liang
    Abstract:
    Multiple-input multiple-output (MIMO) antenna technology is promising for high-speed wireless communications without increasing the transmission band- width. Space time coding (STC) is a scheme that employs multiple antennas to increase transmission rate or to improve transmission quality. STC is used widely in mobile cellular networks, wireless local area networks (WLAN)...

  • Applications of mathematical programming techniques in optimal power flow problems

    Creator:
    Li, Ruqi
    Abstract:
    In the past two decades, a great amount of attention has been paid to investigating the economic and safe operation of power systems using modern mathematical techniques. The classic economic dispatch problem, now often called the Optimal Power Flow problem, has been formulated as a mathematical optimization problem and has...
