  • Oscillators and phase locked loops for space radiation environments

    Creator:
    Vandepas, Martin
    Abstract:
    Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...

  • 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...

  • A stochastic time-to-digital converter for digital phase-locked loops

    Creator:
    Ok, Kerem
    Abstract:
    Digital phase-locked loops (PLLs) have been receiving increasing attention recently due to their ease of integration, scalability and performance comparable to their analog counterparts. In digital PLLs, increased resolution in time-to-digital conversion is desirable for improved noise performance. This work describes the design and simulation of a stochastic time-to-digital converter...

  • A multi-bit delta sigma audio digital-to-analog converter

    Creator:
    Wang, Ruopeng
    Abstract:
    Digital-to-analog converters (DACs) with wide dynamic range and high linearity are required for high-end audio applications. A multi-bit delta sigma audio DAC, using a novel gain-correction technique, is described in this thesis. For widely varying on-chip RC time constant, the DAC gain can be accurately controlled by the correction circuitry....

  • 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...

  • Low-power design techniques for low-voltage analog-to-digital converters

    Creator:
    Kim, Min Gyu
    Abstract:
    The demand for portable electronic systems and the continued down-scaling of device dimensions resulted in rapid improvement in the performance of integrated systems. Several low-voltage design techniques have been proposed to operate analog circuits with sub-1V supply. However, these techniques require higher power consumption to achieve large dynamic range while...

  • Design techniques for radiation hardened-phase locked loops

    Creator:
    Nemmani, Anantha Nag
    Abstract:
    Spacecrafts experience radiation in the course of their operation and all electronic equipment on board these spacecrafts has to be designed to withstand the effects of this radiation. This thesis describes the effects of total ionization dose (TID) and single event transients (SET) in phase-locked loops - an important circuit...

  • Design techniques for low-voltage and low-power analog-to-digital converters

    Creator:
    Ahn, Gil Cho
    Abstract:
    With the ever-increasing demand for portable devices used in applications such as wireless communication, mobile computing, consumer electronics, etc., the scaling of the CMOS process to deep submicron dimensions becomes more important to achieve low-cost, low-power and high-performance digital systems. However, this downscaling also requires similar shrinking of the supply...

  • Low noise clocking for high speed serial links

    Creator:
    Brownlee, Merrick
    Abstract:
    As the functionality of digital chips continues to increase dramatically, chip- to-chip communication bandwidths must scale accordingly to avoid constraining the overall system performance. Therefore, high speed transceiver design has be- come an important research topic. In particular, the performance of the circuits that are responsible for timing accuracy are...

    Creator:
    Brown, Matthew Eugene
    Abstract:
    There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...
