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 ...

A Zener diode is the simplest known type of voltage limiter (Figure 1) As soon as the voltage exceeds the rated voltage of the Zener diode, a current can flow through the diode to limit the voltage.

I'm in software, and I'm an idiot. When doing hardware design, I'm therefore limited to very simple circuits, or following premade schematics. This time, though, I can't seem to Google up everything ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...

The LM317 voltage regulator is well know for its versatility and ability to perform many different and varied functions. The standard and classic is the adjustable positive voltage regulator with a ...

For the longest time, Zener diode regulators have been one of those circuits that have been widely shared and highly misunderstood. First timers have tried to use it to power up their experiments and ...

Riffling through my box of old projects, I came upon a project that I had built in the 80’s — an Automotive Multimeter which was published in the Dutch/British Elektor magazine. It could measure low ...

The diode is a fundamental component you must understand if you want to grow your electronics prowess. So today, we’re going to take a quick look at what a diode is, then look at 4½ uses for a diode ...
