Okay, I'm building a serial link cable for my TI calculator and the plans call for two zener diodes. What exactly is a zener diode? Is that just a regular diode, because I have some diodes, and if ...

In many applications where the input is not under system control but rather connects to the outside world, such as test equipment, instrumentation, and some sensing equipment, it is possible for input ...

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 ...

The filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it and produces light as a result. Taking ...

Editors’ Note: This segment is adapted from Chapter 3 of Power Supplies for LED Driving by Steve Winder. We have seen in Chapter 2 that an LED behaves like a constant voltage load with low equivalent ...
