  • Correlated level shifting as a power-saving method to reduce the effects of finite DC gain and signal swing in opamps

    Creator:
    Gregoire, B. Robert
    Abstract:
    This thesis presents methods to reduce the effects of finite opamp DC gain, output voltage swing limitations in opamps, and component mismatches. The primary contribution of this thesis is a new switched-capacitor method named correlated level shifting (CLS). CLS enables true rail-to-rail operation by storing an estimate of the desired...

  • Design of low power 2.4GHz CMOS LC balanced oscillators with low phase noise and large tuning range

    Creator:
    Seshan, Nilakantan
    Abstract:
    The design of two 2.4GHz CMOS LC balanced oscillators in the 0.25μm National BiCMOS process for Bluetooth specifications is presented. These oscillators achieve low phase noise with low power consumption. At a frequency offset of 500KHz from the 2.11GHz carrier, the measured phase noise is -101.9dBc/Hz for the NMOS oscillator...

  • Power-Efficient Design Techniques and Architectures for Scalable Submicron Analog Circuits

    Creator:
    Xu, Yang
    Abstract:
    As the CMOS process scales down to submicron, digital circuit performance improves, while reduced supply voltage and lower transistor intrinsic gain make it difficult to implement analog circuits in a power efficient manner. Therefore, it has become advantageous to shift more analog signal processing functions conventionally realized in voltage (analog)...

  • Wide-bandwidth, high-resolution delta-sigma analog-to-digital converters

    Creator:
    Zanbaghi, Ramin
    Abstract:
    There is a significant need in recent mobile communication and wireless broadband systems for high-performance analog-to-digital converters (ADCs) that have wide bandwidth (BW>5-MHz) and high data rate (>100-Mbps). A delta-sigma ADC is recognized as a power-efficient ADC architecture when high resolution (>12-b) is required. This is due to several advantages...

  • Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

    Creator:
    Guerber, Jon
    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...

  • Analysis and modeling of single-ended and differential spiral inductors in silicon-based RFICs

    Creator:
    Watson, Adam C.
    Abstract:
    A new comprehensive wide-band compact modeling methodology for single-ended spiral inductors and differential spiral inductors is presented. The new modeling methodology creates an equivalent circuit model consisting of frequency-independent circuit elements for use in circuit simulators. A fast automated extraction procedure is developed for determining the circuit element values from...

  • Automated verilog-to-layout synthesis of ADCs using custom analog cells

    Creator:
    Waters, Allen
    Abstract:
    A procedure for automating the design and layout of analog-to-digital converters (ADCs) is presented. This procedure makes use of the existing synthesis and place-and-route tools that are common in digital circuit design. A method for adding rudimentary analog cells to the standard library is described, allowing the designer to synthesize...

  • Design techniques for PVT tolerant phase-locked loops

    Creator:
    Wu, Ting
    Abstract:
    The continued scaling of deep-submicron CMOS technology enables low-voltage high-frequency phase-locked loops (PLLs) to be fully integrated in complex mixed-signal systems. However, fluctuations due to the manufacturing process and variations in environmental conditions, such as supply voltage and temperature, are also significantly increased. As a result, the performance of PLLs...
