A recent model of an internally or externally controlled ideal switch is described. General nonperiodical switching is considered. No limitations regarding the circuit structure and complexity are imposed. Application to variety of electronic circuits is demonstrated. Special attention is paid to electronic power circuits such as switched power supplies and converters.

In recent years, three separate efforts took place at three different institutions to provide an electronic circuit modeling and simulation capability within the framework of Modelica, an object-oriented general-purpose environment for the modeling of physical systems. In order to be generally usable, no domain-specific knowledge is hard-coded into the Modelica software. Modelica only understan...

This paper provides electronic implementation of electrocardiograph (ECG) circuit by using instrumentation amplifier (IA) as bio-potential amplifier in such a manner which reduces noise, common voltage, DC offset value and RF interference from the existing circuit.Noise and common voltage can be removed from ECG using driven right leg circuit or by using isolator circuit. DC offset can be remov...

Enforcing copyright laws aimed at intellectual property protection of electronic design is generally considered a hard task. The difficulty is in discovering infringements effectively and proving them as such in a court of law. While reverse engineering is a widely used and legal tool to extract schematics from fabricated integrated circuits, determining that a given circuitry is trivially deri...

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...

A novel multi-cellular electronic circuit capable of evolution and development is described here. The circuit is composed of identical cells whose shape and location in the system is arbitrary. Cells all contain the complete genetic description of the final system, as in living organisms. Through a mechanism of development, cells connect to each other using a fully distributed hardware routing ...

Stochastic and coherence resonances appear in nonlinear systems subjected to an external source of noise and are characterized by a maximum response at the optimal value of the noise intensity. This paper shows experimentally that it is possible to observe them in a chaotic system. To this end we have analysed an electronic Chua circuit running in the chaotic regime and added noise to its dynam...

Enforcing copyright laws related to circuit design is usually hard, since discovery and proof of infringements are required beyond reasonable doubt. Proving that a given circuitry is trivially derived from a patented technique or method is in general a painstakingly slow task, often requiring reverse-engineering and forensic analysis of fabricated chips. These techniques are so complex that the...
