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 ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

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 ...

Why conventional buck converters can struggle with high step-down non-isolated DC-DC conversion. How hybrid converter topologies can improve efficiency using charge-pump-assisted buck regulation.
