In this paper, lumped models for vias in multilayered PCBs and their extraction are presented. Thereby, the model elements are derived from physics. It is possible to estimate the parameters of the lumped models using analytical formulas, but more precise values can be derived from vector network analyser measurements or 3d-field solver computations of a real via geometry. Two method for the extraction...
The speeds of computers need to increase. A limitation to increasing this speed is the layout design of printed circuit boards (PCB's). One of the critical limiting factors of the PCB is the orientation of differential capacitors with respect to one another. This paper determines the optimal orientation of these capacitors in order to reduce the return loss (DS11) from crosstalk as the speeds of computers...
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the double...
