Characterization and models for multi-gigabit signaling is an important issue in modern digital system. A good physical based model relies on a precise characterization of the test board. Typically, the characterization of the test board is associated with scattering matrix parameter measurement, which can be done with a VNA (Vector Network Analyzer) in the frequency-domain or a TDR (Time Domain Reflectometer) in the time-domain. The commonly used launch techniques on PCBs (Printed Circuit Boards) associated with the VNA or TDR measurement in the microwave frequency range use SMA or 3.5 mm connectors, in edge-launch or vertical-launch fashions. The transition between …

Estimation Of Current From Near-Field Measurement, Haixiao Weng, Daryl G. Beetner, Richard E. Dubroff, Jin Shi Aug 2005

Estimation Of Current From Near-Field Measurement, Haixiao Weng, Daryl G. Beetner, Richard E. Dubroff, Jin Shi

Electrical and Computer Engineering Faculty Research & Creative Works

Knowledge of high-frequency currents in the chip and chip-package are necessary for EMI analysis and prediction, though measurement of these currents may be difficult to obtain in many cases. One possibility is to estimate currents from near-field scan data. In this paper, measurements were made of the magnetic field over a simple circuit and a chip package. The current flowing in the circuit and the chip lead frame was estimated from the compensated near-field data and compared with measurements made directly on the pins. Estimation was performed both with and without structural information of the lead frame. The susceptibility of …

Comparison Of Near-Field Millimeter-Wave Probes For Detecting Corrosion Precursor Pitting Under Paint, Mohammad Tayeb Ahmad Ghasr, Sergey Kharkovsky, R. Zoughi, Russell A. Austin

Electrical and Computer Engineering Faculty Research & Creative Works

Aircraft structural components such as wings and fuselages are constantly exposed to harsh environments, which make them susceptible to corrosion initiation and growth. To complicate matters, corrosion is normally hidden under paint and primer and cannot be visually detected until significant corrosion has occurred, causing the paint to blister. Corrosion of this type is usually preceded by the presence of corrosion precursor pitting. Hence, early detection of pitting is a critical issue in the maintenance of an aircraft and its structural components. Near-field microwave nondestructive testing techniques have been successfully used for detection of corrosion under paint, including very small …

Electrical and Computer Engineering Faculty Research & Creative Works

The Space Shuttle Columbia's catastrophic failure is thought to have been caused by a dislodged piece of external tank spray on foam insulation (SOFI) striking the left wing of the orbiter causing significant damage to some of the reinforced carbon/carbon leading edge wing panels. Microwave and millimeter wave nondestructive evaluation methods have shown great potential for inspecting SOFI for the purpose of detecting anomalies such as small air voids that may cause separation of the SOFI from the external tank during a launch. These methods are capable of producing relatively high-resolution images of the interior of SOFI particularly when advanced …

Aim of this paper is the validation in both frequency and time domain of the procedure to extract fully H-Spice compatible equivalent circuits of structures on printed circuit boards. The procedure is initiated by standard measurement of scattering parameters between 40MHz to 20GH. After the extraction of the equivalent circuit, the computed scattering parameters are compared with those measured. The same equivalent circuit is also used for transient analysis in order to compare TDR measurement and eye-pattern to a pseudo-random bit sequence with those coming from the simulations.

We review fast solvers for Laplace's equation, which is about 10 times faster than the conventional fast multipole method. Then we review the physics of low-frequency electromagnetics, and the relevant low-frequency method of moments. We describe a fast solver that allows us to solve over one million unknowns on a workstation recently. In addition, we demonstrate the applications of these fast integral equation solvers to the lithography problem. In addition, we propose a scheme whereby we first characterize blocks of linear circuits …

Locally Synchronous, Globally Asynchronous Design For Quantum-Dot Cellular Automata (Lsga Qca), Minsu Choi, Nohpill Park

Electrical and Computer Engineering Faculty Research & Creative Works

The concept of clocking for QCA, referred to as the four-phase clocking, is widely used. However, inherited characteristics of QCA, such as the way to hold state, the way to synchronize data flows, and the way to power QCA cells, make the design of QCA circuits quite different from VLSI and introduce a variety of new design challenges and the most severe challenges are due to the fact that the overall timing of a QCA circuit is mainly dependent upon its layout. This fact is commonly referred to as the "layout-timing" problem. To circumvent the problem, a novel self-timed circuit …

Power Transmission Control Using Distributed Max-Flow, Bruce M. Mcmillin, Austin Armbruster, Mariesa Crow, Michael R. Gosnell Jul 2005

Power Transmission Control Using Distributed Max-Flow, Bruce M. Mcmillin, Austin Armbruster, Mariesa Crow, Michael R. Gosnell

Computer Science Faculty Research & Creative Works

Existing maximum flow algorithms use one processor for all calculations or one processor per vertex in a graph to calculate the maximum possible flow through a graph's vertices. This is not suitable for practical implementation. We extend the max-flow work of Goldberg and Tarjan to a distributed algorithm to calculate maximum flow where the number of processors is less than the number of vertices in a graph. Our algorithm is applied to maximizing electrical flow within a power network where the power grid is modeled as a graph. Error detection measures are included to detect problems in a simulated power …

Pulse Regulation Control Technique For Flyback Converter, Mehdi Ferdowsi, Ali Emadi, Mark Telefus, Curtis Davis Jul 2005

Pulse Regulation Control Technique For Flyback Converter, Mehdi Ferdowsi, Ali Emadi, Mark Telefus, Curtis Davis

Electrical and Computer Engineering Faculty Research & Creative Works

Pulse regulation, a fixed frequency control technique, is introduced and applied to flyback converter operating in discontinuous conduction mode (DCM). The control parameters are designed in a way that the converter operates as close as possible to the critical conduction mode. In contrast to the conventional pulsewidth modulation control scheme, the principal idea of pulse regulation is to achieve output voltage regulation using high and low-power pulses. Pulse regulation is simple, cost effective, and enjoys a fast dynamic response. The proposed technique is applicable to any converter operating in DCM. However, this work mainly focuses on flyback topology. In this …

Increasing Student Commitment To Class Preparation, Susan L. Murray

Engineering Management and Systems Engineering Faculty Research & Creative Works

Most of us know the rule-of-thumb that students should spend a certain number of hours outside of class studying for every hour in class. Unfortunately, students often develop the view that it is more efficient to come to class and have the instructor cover the material and then only study material that was emphasized or unclear. As faculty members this results in the dilemma of either assuming the students are not prepared and lecturing over basic material or trying to require the students to prepare. Some use readiness quizzes covering the required readings. Some try to intimidate, calling on students …
