The Amplitude and phase of surface acoustic waves can be characterized using a laser beam and photodiode detector. This paper describes a technigue for charactarizing waves using the double photodiode method. This method is a modification of the knife-edge method, and involves focusing a laser beam to a beam spot...
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...
The electrical performance of on-chip interconnects has become a limiting factor
to the performance of modern integrated circuits including RFICs, mixed-signal
circuits, as well as high-speed VLSI circuits due to increasing operating frequencies,
chip areas, and integration densities. It is advantageous to have fast and accurate
closed-form expressions for the...
In high-frequency circuit design, performance is often limited by the quality
of the passive components available for a particular process. Specifically, spiral
inductors can be a major bottle-neck for Voltage-Controlled Oscillators (VCOs),
Low-Noise Amplifiers (LNAs), mixers, etc. For designers to correctly optimize a circuit
using a spiral inductor, several frequency-domain...
A new method for accelerating the Upstream Corner Balance (UCB) discretization
of the equation of transfer is introduced. The inconsistent acceleration equations
for the UCB discretization are derived by applying the "Modified 4-Step" diffusion
synthetic acceleration technique not to the UCB discretization, but instead to the
simple corner balance (SCB)...
Imaging spectra of plant tissues yield considerable potential and useful information
for basic studies and agriculture practice. We constructed an imaging spectrophotometer
with spectral range from 400 nm to 1100 nm, which was used to study various
physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...
Nanolaminate dielectrics combine two or more insulating materials in a many-layered film. These structures can be made to significantly outperform films composed of a single one of their constituent materials by adjusting the composition ratio, arrangement, and size of the component layers. In this work, atomic layer deposition (ALD) is...
As the semiconductor industry works to integrate increasingly more "non-CMOS" devices onto CMOS ICs, compact model development has become an important step in the circuit/system verification tool flow. This research focuses on the two- and three-dimensional modeling of the physical phenomena that occur in nanoscale magnetic devices. This includes the...
