Generally speaking, we try to avoid operating diodes in their reverse breakdown region, but Zener diodes are the exception to this rule. Generally speaking, we try to avoid operating diodes in their ...

My recent columns discussed the physics and applications of discrete-zener-diode references, and the conclusion they reached is that discrete zener diodes make poor references because of tolerance ...

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 ...

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 ...
