  • Design of CMOS switched-current filters

    Creator:
    Fiez, Theresa S.
    Abstract:
    The design and implementation of Switched-Current (SI) ladder filters is described. SI filters require only a standard digital CMOS process and the power supply voltage requirement is low. SI circuits also can be potentially operated at higher frequencies than Switched-Capacitor (SC) filters due to the low-impedance wideband nodes of the...

  • Two dimensional numerical simulation of a non-isothermal GaAs MESFET

    Creator:
    Lin, Angela A.
    Abstract:
    The low thermal conductivity of gallium arsenide compared to silicon results in self-heating effects in GaAs MESFETs that limit the electrical performance of such devices for high power applications. To date, analytical thermal models of self heating in GaAs MESFETs are based on the assumption of a uniformly heated channel....

  • Hot electron transport and relaxation in quantum wells and superlattices

    Creator:
    Lary, Jenifer Edith
    Abstract:
    Electron transport and relaxation may be substantially different in low-dimensional systems compared to that observed in bulk material. In the present work, Monte Carlo models are used for the solution to the Boltzmann transport equation, with scattering rates calculated quantum mechanically for superlattice and quantum wells. Carrier relaxation following optical...
