  • Design of high efficiency step-down switched capacitor DC/DC converter

    Creator:
    Ma, Mengzhe
    Abstract:
    Recently, switched capacitor DC/DC converters are extensively used in portable electronic devices because they feature many advantages, such as high efficiency, small package, low quiescent current, minimal external components and low cost. In this thesis, two step-down switched capacitor DC/DC converters are designed. One has the fixed output options 1.5V,...

  • Low voltage techniques for pipelined analog-to-digital converters

    Creator:
    Carnes, Joshua Kenneth
    Abstract:
    To realize pipelined ADCs in deep-submicron processes, low voltage techniques must be developed to work around problems created by limited supply voltages such as the floating switch dead zone, reduced SNR, and reduced OpAmp performance. This thesis analyzes standard and low voltage design issues for pipelined ADCs and proposes a...

  • Ring amplification for switched capacitor circuits

    Creator:
    Hershberg, Benjamin Poris
    Abstract:
    A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail...

  • Continuous time input pipeline ADCs

    Creator:
    Gubbins, David Patrick
    Abstract:
    Analog-to-digital converters (ADCs) convert analog continuous time signals into discrete time, digital format. One precondition that must be met for conventional nyquist rate ADCs is that the input signal must be suitably band-limited to an input bandwidth less than the nyquist frequency. This mandates expensive anti-alias filters which contribute to...

  • Accuracy enhancement techniques in low-voltage high-speed pipelined ADC design

    Creator:
    Li, Jipeng
    Abstract:
    Pipelined analog to digital converters (ADCs) are very important building blocks in many electronic systems such as high quality video systems, high performance digital communication systems and high speed data acquisition systems. The rapid development of these applications is driving the design of pipeline ADCs towards higher speed, higher dynamic...

  • 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...

  • Design techniques for clocking high performance signaling systems

    Creator:
    Hanumolu, Pavan Kumar
    Abstract:
    Scaling of CMOS technology has progressed relentlessly for the past several decades. In order for this unprecedented scaling to benefit the performance of large digital systems, the communication bandwidth between integrated circuits (ICs) must scale accordingly. However, interconnect technology does not scale as aggressively, making communication between chips the major...

  • Low power scheduling schemes that consider latency and resource constraints at multiple voltages

    Creator:
    Huang, Shyh-Sen
    Abstract:
    Power reduction can be achieved at many different levels, such as architecture, algorithm, logic, and transistor levels in circuit design. This thesis focuses on low power scheduling at the algorithm level. We present a latency-constrained scheduling and a latency and resource constrained scheduling, which minimize power consumption for the resources...

  • Comparison and impact of substrate noise due to clocked and clockless circuitry

    Creator:
    Le, Jim K.
    Abstract:
    Delay insensitive asynchronous circuitry provides significant advantages with respect to substrate noise due to localized switching. The differences between the substrate noise from NULL Convention Logic (NCL) and traditional Clocked Boolean Logic (CBL) are described and analyzed based on measured results. A test chip fabricated in the TSMC 0.25 um...

    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...
