The extraction of circuit models for package power supply distribution systems from the results of full wave EM simulations is addressed. Both time and frequency domain optimizations are used for the extraction. The frequency domain optimization was found to be more reliable. An example is shown for illustration.

A software organization of a new circuit simulator, SAMOC (Switchedcapacitor Analysis of MOs Circuit) is presented in this paper. SAMOC employs extremely simplified, piecewise linear, resistive models to represent the semiconductor devices such as MOS transistors and ideal diodes in the simulated circuits. SAMOC also supports ideal switches and ideal capacitors for analyzing switched-capacitor ...

The Information extracted from log files of computing systems can be considered one of the important resources of information systems. In the case of Integrated Circuit design, log files generated by design tools are not exhaustively exploited. The logs of this domain are multi-source, multi-format, and have a heterogeneous and evolving structure. Moreover, they usually do not respect the gramm...

Printed circuit boards (PCBs) are a valuable source of raw materials for metal recycling considering that base concentration analyses have confirmed PCB powders multimetallic in nature and contain high concentrations Cu, Zn, Ni, Fe. Given minerals not renewable resources, these metals can be recycled through hydrometallurgical processes. In this study, we determined 2 M sulfuric acid, 0.55 MPa ...
