Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Inductance in IC interconnects is becoming increasingly significant for designs operating at GHz frequencies. The damping effect of high resistance in narrow signal wires in sub 0.13um designs reduces ...

There is a wide need for position, motion, and proximity sensing using low power for various applications. Capacitive, inductive, and Hall effect sensors are among the approaches for today’s low-power ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

Legacy designs of variable frequency drives (VFDs) used optocouplers or pulse transformers for isolation and mated them together with gate driver ICs. A more integrated approach, though, uses ...
