As clock speeds increase into the gigahertz regime and rise times decrease into the pico-second regime, the interaction between capacitors and power/ground planes of a package, or board on which they are mounted becomes vitally important to the performance of a power delivery system. Capacitors pose the biggest challenge for integration in packages due to the large capacitance required for decoupling...

In this paper, a novel improved simulated annealing genetic algorithm is proposed based on the analysis of the properties of traditional simulated annealing (SA) and simulated annealing genetic algorithm (SAGA). The parameter of population entropy is used in SAGA, which can explore the solution space efficiently and keep the population diversity. The improved algorithm is further applied to impedance...
The parameters to distinguish breast cancer and the surrounding tissues are studied in this paper. By studying the impedance data of the 46 groups of sample, five parameters are extracted, which are projection slopes, the center coordinates of the COLE-COLE curve, the area ratio of difference curve, the fitting slope of difference curve, and the span of difference curve. During the quantitative analysis,...
The effect of the number of the shorting vias on the power integrity of multi-layered structures has been demonstrated in this paper. Following that, an empirical design rule for the fewest number of the shorting vias is proposed to maintain the original power integrity and reduce the cost at the same time. For validation, the design concept is also realized in a real package structure at last.
