  • Design of low OSR, high precision analog-to-digital converters

    Creator:
    Rajaee, Omid
    Abstract:
    Advances in electronic systems have lead to the demand for high resolution, high bandwidth Analog-to-Digital Converters (ADCs). Oversampled ADCs are well- known for high accuracy applications since they benefit from noise shaping and they usually do not need highly accurate components. However, as a consequence of oversampling, they have limited...

  • A multi-bit delta sigma audio digital-to-analog converter

    Creator:
    Wang, Ruopeng
    Abstract:
    Digital-to-analog converters (DACs) with wide dynamic range and high linearity are required for high-end audio applications. A multi-bit delta sigma audio DAC, using a novel gain-correction technique, is described in this thesis. For widely varying on-chip RC time constant, the DAC gain can be accurately controlled by the correction circuitry....

  • Automated synthesis of analog to digital conversion

    Creator:
    Weaver, Skyler
    Abstract:
    This thesis describes circuit architectures and techniques that facilitate the automatic synthesis and fabrication of analog-to-digital converters (ADCs). Since automated synthesis already exists for digital circuits and is part of the digital circuit design flow, this work demonstrates the feasibility of ADC synthesis with little or no modification to presently...

  • Efficient use of time information in analog-to-digital converters

    Creator:
    Hu, Yue
    Abstract:
    Time-domain data conversion has recently drawn increased research attention for its highly digital nature in favor of process technology scaling. Also, as the time information being carried by binary voltage, time-domain operation is much less sensitive to voltage noise compared to conventional voltage domain operation. However, for analog-to-digital converter (ADC)...

  • 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...

  • Low-power design techniques for low-voltage analog-to-digital converters

    Creator:
    Kim, Min Gyu
    Abstract:
    The demand for portable electronic systems and the continued down-scaling of device dimensions resulted in rapid improvement in the performance of integrated systems. Several low-voltage design techniques have been proposed to operate analog circuits with sub-1V supply. However, these techniques require higher power consumption to achieve large dynamic range while...

  • Low power design techniques for analog-to-digital converters in submicron CMOS

    Creator:
    Musah, Tawfiq
    Abstract:
    Advances in process technologies have led to the development of low-power high speed digital signal processing blocks that occupy small areas. These advances are critical in the development of portable electronic devices with small feature size and long battery life. However, the design of analog and mixed-signal building blocks, especially...

  • A fully digital technique for the estimation and correction of the DAC error in multi-bit delta sigma ADCs

    Creator:
    Wang, Xuesheng
    Abstract:
    This thesis proposes a novel fully digital technique for the estimation and correction of the DAC error in multi-bit delta sigma ADCs. The structure of the DAC error is indicated through a simple model for unit-element based DACs. The impact of the DAC error on the performance of ADC is...
