  • Resolution enhancement of analog-to-digital converters through computationally simple digital filtering

    Creator:
    Zahl, Eric L.
    Abstract:
    The resolution of analog-to-digital converters can be distinguished as absolute resolution, or average resolution. This study reviews average resolution enhancement techniques and proposes a method which is particularly applicable as a low-cost modification to a high-speed waveform acquisition system. This method uses oversampling combined with computationally simple digital filtering to...

    Maleki, Mohammad
    Abstract:
    This thesis describes the development of a flash analog-to-digital converter based on current-mode technique. The advantages of current -mode technique are higher speed, smaller chip area, and simple division of reference current based on current mirror. A current-mode comparator is designed consisting of a cascode current mirror and a current...

  • Adaptive correction techniques for delta-sigma A/D converters

    Creator:
    Abdennadher, Salem
    Abstract:
    Oversampling analog-to-digital and digital-to-analog converters are gaining more popularity in many signal processing applications. Delta-sigma modulators are used in practical applications of oversampling systems because of their apparent practical advantage over other oversampling converters in terms of insensitivity to the inevitable imperfection of the analog circuitry. In Δ∑ modulators, analog...

  • Adaptive noise cancellation for second-order delta-sigma A/D converters

    Creator:
    Bribech, Habib
    Abstract:
    Oversampled analog-to-digital (A/D) converter architectures have been receiving increased attention for high-precision A/D converters. These architectures offer the means of exchanging resolution in time for that in amplitude. Among these oversampled A/D converters, delta-sigma modulators are the most popular method used due to their simplicity in the analog circuitry. The...
