  • Analog integrated circuit design using GaAs C-HFETs

    Creator:
    Gupta, Rakhee
    Abstract:
    Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

  • Failure analysis of Muller-C-element

    Creator:
    Chew, Oonpin
    Abstract:
    Asynchronous circuits have recently been a breakthrough in many high performance computers. The concept of asynchronous circuits which started a long time ago has slowly grasped the attention of many designers. The Muller-C-element is an important control block in many asynchronous designs and therefore it is important to understand some...

  • 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...

  • Monte Carlo device modeling applications on parallel computers

    Creator:
    Pennathur, Shankar S.
    Abstract:
    One of the ways of countering the ever increasing computational requirements in the simulation and modeling of electrical and electromagnetic devices and phenomena, is the development of simulation and modeling tools on parallel computing platforms. In this thesis, a previously developed Monte Carlo parallel device simulator is utilized, enhanced, and...

  • Synchronization in a CMOS technology

    Creator:
    Flannagan, Stephen T.
    Abstract:
    The problem of synchronization arises in the interaction among digital systems not sharing a common clock reference. The reliability of synchronizers is related to metastable operation of bistable elements. Because of its subtle nature, the phenomenon until recently was not widely researched. However, the literature now contains a sound theoretical...

  • 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....

  • Modeling and characterization of hemt devices

    Creator:
    Chang, Chujyh
    Abstract:
    Different gate length (0.5 μm 16 μm) Al GaAs/GaAs and AIGaAs /InGaAs High Electron Mobility Transistors were electrically characterized in order to compare the room temperature DC device performance with one-dimensional device models. Model parameters such as the channel mobility and source/drain series resistances are extracted from independent measurement of...

    Abstract:
    Split and normal gate A1GaAs /GaAs MODFETs were fabricated along with the ohmic test structures and the Hall bar geometries. The DC characteristics of normal gate transistors were evaluated at room temperature and at 77K and the threshold voltages were extracted from the measurements and compared to the theoretical results....
