Suppose the zener diode on the circuit has a breakdown voltage of 10 V. What are the minimum and maximum zener currents? The applied voltage may vary from 20 to 40 V. Ideally, a zener diode acts like ...
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 ...
