  • A survey on continuous-time modulators : theory, designs and implementations

    Creator:
    Gao, Xiaoran
    Abstract:
    Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...

  • Efficient power conversion interface circuits for energy harvesting applications

    Creator:
    Le, Triet T.
    Abstract:
    Harvesting energy from the environment for powering micro-power devices have been increasing in popularity. These types of devices can be used in embedded applications or in sensor networks where battery replacement is impractical. In this dissertation, different methods of energy harvesting from the environment are explored as alternative sources of...

  • An efficient modeling approach for substrate noise coupling analysis with multiple contacts in heavily doped CMOS processes

    Creator:
    Özis, Hatice Dicle
    Abstract:
    A computationally efficient and accurate substrate noise coupling model for multiple contacts in heavily doped CMOS processes is presented and validated with simulations and experimental data. The model is based on Z parameters that are scalable with contact separation and size. This results in fast extraction of substrate resistances for...

  • A substrate noise coupling model for lightly doped CMOS processes

    Creator:
    Sadate, Aline C.
    Abstract:
    This thesis presents a design-oriented model for lightly doped CMOS substrates. The model predicts the substrate noise coupling between noisy digital and sensitive analog blocks in the early stages of the design. The model scales with the size and separation of these blocks and it is validated with device simulations...

  • Automated model parameter extraction for noise coupling analysis in silicon substrates

    Creator:
    Peterson, Brett
    Abstract:
    An automated method, requiring the fabrication of a small set of test structures, efficiently extracts the coefficients of Z-parameter based macromodels. The extraction approach has been validated for both heavily and lightly doped substrates and can be applied to a variety of technologies. After the parameters of a macromodel have...

  • 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....

  • Novel design and implementation of a permanent magnet linear tubular generator for ocean wave energy conversion

    Creator:
    Prudell, Joseph H.
    Abstract:
    The world’s energy consumption is growing at an alarming rate and the need for renewable energy is apparent now more than ever. Estimates have shown that optimization of the extraction of energy from the ocean could significantly aid the world’s quest for sustainable and affordable energy services for all. From...

  • Architecture design of multiplexed incremental analog-to-digital converters

    Creator:
    Zhang, Zhiqing
    Abstract:
    Analog-to-Digital Data Converters (ADCs) used in instrumentation and measurements often require high absolute accuracy, including excellent linearity and negligible dc offset. Incremental data converters (IDCs) provide a solution for such measurement applications. Since IDCs are essentially delta-sigma converters with reset operation before each conversion, they retain most of the advantages...

  • Efficient VLSI architectures for MIMO and cryptography systems

    Creator:
    Li, Qingwei
    Abstract:
    Multiple-input multiple-output (MIMO) communication systems have recently been considered as one of the most significant technology breakthroughs for modern wireless communications, due to the higher spectral efficiency and improved link reliability. The sphere decoding algorithm (SDA) has been widely used for maximum likelihood (ML) detection in MIMO systems. It is...
