  • Design and analysis techniques for nano-joule ADCs and sampling linearity

    Creator:
    Brown, Thomas (Thomas William)
    Abstract:
    Two aspects of ADC system performance are addressed in this work. First, the combination of the ADC and its associated reference are co-designed for an energy constrained remote sensing system. Second, sampling linearity is mathematically analyzed as a function of frequency to provide enhanced understanding into an ADC's requisite sampling...

  • Wide-bandwidth, high-resolution delta-sigma analog-to-digital converters

    Creator:
    Zanbaghi, Ramin
    Abstract:
    There is a significant need in recent mobile communication and wireless broadband systems for high-performance analog-to-digital converters (ADCs) that have wide bandwidth (BW>5-MHz) and high data rate (>100-Mbps). A delta-sigma ADC is recognized as a power-efficient ADC architecture when high resolution (>12-b) is required. This is due to several advantages...

  • Design of a 14-bit continuous-time Delta-Sigma A/D modulator with 2.5MHz signal bandwidth

    Creator:
    Li, Zhimin
    Abstract:
    In recent years, there has been growing interest in both industry and academia to use continuous-time (CT) Δ-Σ A/D converters for wideband wireless and wireline communication applications. So far no reported CT Δ-Σ A/D modulator achieves 14-bit or higher dynamic range (DR) with more than 2MHz signal bandwidth (equivalently 4MS/s)....

  • Adaptive, wideband analog-to-digital conversion for convergent communication systems

    Creator:
    Batten, Robert D., 1973-
    Abstract:
    The exponential rate of advances in modern communication devices in the last several years have brought us higher levels of functionality and performance as well as reductions in physical size and power consumption. To continue this rate of advancement, next generation systems require wider bandwidth and higher resolution ADCs. Additionally,...
