  • 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...

  • 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...

  • 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...

  • Generalized radix design techniques for low-power, low voltage pipelined and cyclic analog-digital converters

    Creator:
    Sharma, Vivek
    Abstract:
    This thesis proposes a novel technique for the design of pipelined and cyclic ADCs utilizing generalized radix gain stages. Several models have been proposed for the optimization of high performance pipelined ADCs by various researchers. This work builds upon them, using a simple but accurate model to estimate the optimal...

  • Design of current-mode track and hold circuits

    Creator:
    Chennam, Madhusudhan
    Abstract:
    A differential current-mode track-and-hold (T/H) amplifier is used to sample an analog input signal. A new closed-loop current-mode architecture has been developed that overcomes the stability problems associated with closed-loop architectures. The T/H circuit has been fabricated in a 0.35-μm quad-metal, double-poly CMOS process. The measured total harmonic distortion (THD)...

  • Error canceling low voltage SAR-ADC

    Creator:
    Wen, Jianping
    Abstract:
    The design of a switched capacitor successive approximation A/D converter is discussed in this thesis. This design adopts a novel capacitance mismatch error cancellation algorithm proposed in references [25, 27]. Detailed charge domain analysis is given in this thesis, which results in an improvement of the proposed algorithm by tracing...

  • Power efficient analog-to-digital converters using both voltage and time domain information

    Creator:
    Oh, Taehwan
    Abstract:
    As advanced wired and wireless communication systems attempt to achieve higher performance, the demand for high resolution and wide signal bandwidth in their associated ADCs is strongly increased. Recently, time-domain quantization has drawn attention from its scalability in deep submicron CMOS processes. Furthermore, there are several interesting aspects of time-domain...

  • Time-based noise-shaping techniques for time-to-digital and analog-to-digital converters

    Creator:
    Young, Brian LeRoy
    Abstract:
    In this dissertation, time-based signal processing techniques and their applications in oversampling and noise-shaping data converters are examined. These techniques demonstrate the ability to shift the burden of high performance analog circuits from the compressed voltage-domain to the augmented time-domain. First, the potential of high order noise-shaping and phase-domain feedback...

    Abstract:
    In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...
