  • 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...

  • Design of high-speed summing circuitry and comparator for adaptive parallel multi-level decision feedback equalization

    Creator:
    Gao, Hairong
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective sampled signal processing technique to remove inter-symbol interference (ISI) from disk read-back signals. Parallelism which doubles the symbol rate can be realized by utilizing the characteristic of channel response and decision feedback equalization algorithm. A mixed-signal IC implementation has been chosen for...

  • Low power high resolution data converter in digital CMOS technology

    Creator:
    Zheng, Zhiliang
    Abstract:
    The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...

  • 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...

  • 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...

    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...
