Circuit models are the heart of worst-case circuit analysis (WCCA). For simulations to be valid, you must gather and vet models or create them yourself; you can't usually rely on the manufacturer's ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and ...

Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow ...

To make something work using electricity there needs to be an electrical circuit; a circuit is a complete loop that electricity can move around. Electricity moves from the power source (the battery or ...

Last month, we began this series talking about closed circuit TV monitoring. In this month's article, we will begin covering the components of video systems. We won't get through all of them in one ...

(Nanowerk Spotlight) Along the way to all-optical devices in communication and information technology, photonic crystals play a significant role. They form a basis material for the future realization ...

There has been enormous progress in recent years toward the development of photonic chips — devices that use light beams instead of electrons to carry out their computational tasks. Now, researchers ...
