Fast methods for extraction and sparsification of substrate coupling
Substrate coupling effects have had an increasing impact on circuit performance in recent years. As a result, there is strong demand for substrate simulation tools. Past work has concentrated on fast substrate solvers that are applied once per contact to get the dense conductance matrix G. We …

An Integrated Tool For High Speed Circuits with Substrate Coupling.
An integrated environment for layout-oriented design of circuits for spatial power combining system is aimed in this study. The simulation environment would include a full-wave electromagnetic simulator and a circuit simulator, fREEDA, with a front engine, which is the major emphasis in this …

Concurrent substrate coupling noise modeling and active noise reduction methodology for mixed-signal physical design
… analog circuits, signal contamination caused by substrate coupling noise is a critical issue. Fast digital transients can produce noise harmful to the sensitive analog circuits. The noise can be coupled from noisy devices and interconnects into the common substrate and coupled into analog …

Methodologies for Broadband Electromagnetic Modeling of on-Chip Semiconductor Substrate Noise
For a full-wave modeling of the substrate coupling problem the thesis elaborates on a number of features for the time domain finite integration technique (FIT), a volumetric discretization scheme, aimed at improving its computational performance for the type of geometrical characteristics …

A STUDY OF CERTAIN ELECTROMAGNETIC INTERACTIONS AMONG HIGH OPTICAL CONDUCTIVITY NANOSPHERES AND DIELECTRIC HALF-SPACES
<p>Electromagnetic coupling between a sphere and a semi-infinite substrate, and among several spheres present in the form of a composite were studied in this dissertation. Specifically, spheres made of noble metals such as Ag, Au and Cu and relatively high refractive index substrates and composite …

Microwave CMOS VCOs and Front-Ends - using integrated passives on-chip and on-carrier
… realized in a standard CMOS process the substrate coupling results in a degraded Q. The quality factor can, however, be improved by moving the passive components off-chip and integrating them on a low loss carrier. This thesis therefore features microwave front-end and VCO designs in …
