  • Low-voltage pipeline A/D converter

    Creator:
    Wu, Lei
    Abstract:
    Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor (SC) circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low voltage conditions. There exist three techniques to solve the problem, but with their...

  • Analysis and design of bandpass delta-sigma A/D converters

    Creator:
    Zhai, Dalun
    Abstract:
    A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

  • A subranging analog to digital converter using four bit pipepline

    Creator:
    Press, Stephen E.
    Abstract:
    This thesis presents the design of a 10 bit Analog to Digital Converter which consists of a 6 bit flash followed by a 4 bit pipeline architecture. The total system is described and the 4 bit pipeline is implemented on a bipolar process. The objective of this research is to...

  • Digital implementation of a mismatch-shaping successive-approximation ADC

    Creator:
    Coe, Matthew T.
    Abstract:
    Utilizing a two-capacitor topology, the digital implementation of an audio-band successive-approximation analog-to-digital converter (ADC) is explored in the context of mismatch-shaping where the mismatch estimates are accurate to the first order. A second-order Δ∑ loop was found to be effective in system simulations given a 0.1% capacitor mismatch. Spectral analysis...

  • 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...

  • Compensation techniques for cascaded delta-sigma A/D converters and high-performance switched-capacitor circuits

    Creator:
    Sun, Tao
    Abstract:
    This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC circuits. A CDS technique...

  • Improving a sampled-data circuit simulator for Delta-Sigma modulator design

    Creator:
    Hayward, Roger D.
    Abstract:
    Delta-Sigma Modulator-based Analog-to-Digital converter design is an active area of research. New topologies require extensive simulations to verify their performance. A series of improvements were made to an existing circuit simulation package in order to speed the simulation process for the designer. Various examples of these improvements are presented in...

    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...

    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...
