Current regulators (non-switchable and switchable) are a new family of useful and versatile devices targeted for use in communications, networking and power conversion circuits. Current regulators (or ...

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 ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
