The evacuation of bulk electrical power over long distances can be done mainly by high voltage alternating current (HVAC) ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

The following application note shows how to create a circuit that converts the low output current from a photo-diode into a fast-responding voltage. To view the application note, click on the URL ...
