In the last years, computer simulation has reached a significant position in the investigation and development of technical products. Simulation programmes and computer utilization have found application also in the area of electrical devices. At our workplace we have used simulation programmes for many years to investigate transient phenomena mainly at short-circuit current breaking in miniatu...

Integrated circuit designers have relied on SPICE as their premier EDA tool long before digital system designers began using HDL simulators or logic synthesis. Today tools for computer architecture design lack standard support for multiand many-core designs. We propose using circuit models to describe the multiple processor architecture to motivate a circuit based design approach applied to a c...

recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. at the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver int...

A time-delay chaotification approach can be applied to the Chua’s circuit by adding a small-amplitude time-delay feedback voltage to the circuit. The chaotic dynamics of this newly derived time-delay Chua’s circuit is studied by theoretical analysis, verified by computer simulations as well as by circuit experiments.

all practical digital circuits are usually a mixture of combinational and sequential logic. flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. the concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

echnology computer-aided design (TCAD) is the software tool set that allows integrated circuit T (IC) tech nologists to develop new processes and devices without having to build costly test lots. TCAD can potentially provide process engineers the same benefits that electronic circuit CAD (ECAD) has provided to circuit designers. Circuit designers can design, lay out. and test new circuits witho...

This thesis is an exercise to investigate the various methods of creating an equivalent circuit model for a high-speed digital printed circuit board (PCB) assembly and to perform computer simulation on such a system. The term highspeed printed circuit board is widely accepted in the engineering community to be refering to PCB which is applied to digital system with operating frequency in excess...
