  • Analysis and modeling of planar microstrip spiral inductors on lossy substrates

    Creator:
    Lutz, Richard D.
    Abstract:
    The advent of low-cost RFIC's fabricated in Silicon-based technologies has led to the use of monolithic lumped elements which are located on-die. While it is clearly advantageous to have a high degree of integration and thus fewer off chip elements, parasitic losses due to semiconducting substrate effects can be a...

  • Modeling and characterization of multiple coupled lines

    Creator:
    Tripathi, Alok
    Abstract:
    A configuration-oriented circuit model for multiple coupled lines in an inhomogeneous medium is developed and presented in this thesis. This circuit model consists of a network of uncoupled transmission lines and is readily modeled with simulation tools like LIBRA© and SPICE©. It provides an equivalent circuit representation which is simple...

  • Time domain simulation of multiconductor lossy transmission lines by the method of characteristics

    Creator:
    Orhanovic, Neven
    Abstract:
    A numerical technique to compute the time domain response of multiconductor lossy uniform and nonuniform lines terminated in general nonlinear elements is presented. The technique is based on the generalized method of characteristics. The method transforms the original system of transmission line equations into a system of ordinary differential equations....

  • Monitoring and diagnosis of a multi-stage manufacturing process using Bayesian networks

    Creator:
    Wolbrecht, Eric T.
    Abstract:
    This thesis describes the application of Bayesian networks for monitoring and diagnosis of a multi-stage manufacturing process, specifically a high speed production part at Hewlett Packard. Bayesian network "part models" were designed to represent individual parts in-process. These were combined to form a "process model", which is a Bayesian network...

  • Analysis of planar multi-conductor multilayered structures by network analog method

    Creator:
    McVeety, Joseph J.
    Abstract:
    In this thesis the network analog method is used to analyze various planar multi-conductor structures in multilayered, lossy dielectric media. The method is based on an efficient impedance network representation of the finite difference approximation of Laplace's equation for the electric potential. Using the network analog method, the transmission line...
