  • 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...

  • 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...

  • Low-power double-sampled delta-sigma modulator for broadband applications

    Creator:
    Shen, Weilun
    Abstract:
    High speed and high resolution analog-to-digital converter is a key building block for broadband wireless communications, high definition video applications, medical images and so on. By leveraging the down scaling of the latest CMOS technology and the noise shaping properties, delta-sigma (ΔΣ) ADCs are able to achieve wide-band operation and...

  • Low-power high-resolution delta-sigma ADC design techniques

    Creator:
    Wang, Tao
    Abstract:
    This dissertation presents a low-power high-resolution delta-sigma ADC. Two new architectural design techniques are proposed to reduce the power dissipation of the ADC. Compared to the conventional active adder, the direct charge transfer (DCT) adder greatly saves power by keeping the feedback factor of the active adder unity. However, the...

  • Plasmonic color filter array, high performance analog to digital converter architectures and novel circuit techniques

    Creator:
    Shakya, Jyotindra R.
    Abstract:
    Part I: Plasmonic color filters can be manufactured at lower cost since they can be fabricated in single lithographic process step as compared to Fabry-Perot based filters. In addition, they have narrow passband making resolving sharp features in sample spectrum possible. Due to these benefits, in this thesis, Plasmonic color...

  • 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...

  • Improved design techniques for analog and mixed circuits

    Creator:
    Nishida, Yoshio
    Abstract:
    Although the digital revolution can realize many of past analog components in the digital forms, our world is surrounded with analog signals such as voice, temperature, etc. The bridge between these two worlds is one of key performance limitations among overall systems and it includes analog filters and data converters....

  • 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...

  • Low-voltage switched-capacitor circuits

    Creator:
    Bidari, Emad
    Abstract:
    In recent years, the rapidly growth of CMOS technology has evolved towards submicron and deep-submicron features. Due to smaller device sizes, and significant demand for low-power designs, the maximum allowable power supply voltage is restricted. So far, two solutions; clock boosting and switched opamp schemes have been proposed. The material...
