  • Design considerations for fast-settling operational amplifiers

    Creator:
    Yang, Howard C.
    Abstract:
    The design considerations for fast-settling operational amplifiers (opamps) differ significantly between sampled-data switchedcapacitor (SC) and conventional continuous-time applications. In SC circuits, the shape of the output voltage waveform of an opamp is of no consequence provided that the output settles to within a specified tolerance of its steady-state value prior...

  • LORAN-C receiver position estimation from noisy time-difference data

    Creator:
    Weisshaar, Andreas
    Abstract:
    In order to analyze the accuracy of the navigation system LORAN-C, we have collected time - difference (TD) data from the U.S. west coast chain (9940) at a fixed receiver location (Corvallis, Oregon). The analysis of the TD data shows an unexpected high correlation between the TDs as well as...

  • Variable linear phase digital filters

    Creator:
    Acuna, Fernando R.
    Abstract:
    Linear phase variable filters that are obtained with a frequency transformation of the form cos(ω) = P(cos(W)) were analyzed, where P is a finite degree polynomial, ω is the prototype frequency and W is the transformed filter frequency. A new transformation of third order is proposed. The new variable filter...

  • Applications of mathematical programming techniques in optimal power flow problems

    Creator:
    Li, Ruqi
    Abstract:
    In the past two decades, a great amount of attention has been paid to investigating the economic and safe operation of power systems using modern mathematical techniques. The classic economic dispatch problem, now often called the Optimal Power Flow problem, has been formulated as a mathematical optimization problem and has...

  • A study of the temperature dependence of the DC current-voltage characteristics of AlGaAs/GaAs heterojunction bipolar transistors with application to bandgap voltage reference sources

    Creator:
    Gazeley, William G.
    Abstract:
    The bandgap voltage reference technique, as implemented in Silicon technology, has evolved to a state of advanced development and become the method of choice for temperature independent voltage biasing in integrated circuits. The heterojunction bipolar transistor (HBT), fabricated from epitaxial A1GaAs /GaAs, is developing to a point where basic circuit...

  • Surface recombination velocity and bulk lifetime in GaAs and InP

    Creator:
    Rastegar, Bahador
    Abstract:
    An analytical expression is derived which allows the bulk minority carrier recombination lifetime, t, and the surface recombination velocity, S, to be extracted from a single noncontact photoconductivity decay (PCD) measurement. This analytical expression is rather complex, but can be reduced to a first order approximation. The first order approximation...

  • Instabilities in InP MIS capacitors

    Creator:
    Juang, Min Tzuan
    Abstract:
    The drain current of InP MISPETs is often observed to decrease as a function of time after the application of a positive gate bias which involves an accumulation of electrons in the channel. Various models have been proposed for this drain current drift (DCD) phenomenon. In this thesis, variable-temperature bias-stress...

  • Passive source tracking from spatially correlated angle-of-arrival data

    Creator:
    Haisch, Hansjoerg
    Abstract:
    This thesis presents a simulation technique for the post-detection of a point-source trajectory in an isotropic, stationary random medium. The two-dimensional source location is estimated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions. We assume that the data are collected at discrete, constant time intervals...

  • Optimal control of an induction motor

    Creator:
    Yarimbiyik, Bulent
    Abstract:
    With the development of converters and inverters, it became possible to control the stator current of an induction motor. The differential equations which describe transient behavior of the induction motor are conveniently expressed by transforming the stator and rotor variables to d-q axes rotating at synchronous speed. The transient behavior...
