A capacitor is an essential component in many electrical and electronic circuits. It stores and releases electrical energy when needed, helping regulate voltage and maintain power stability. Over time ...

Abstract: A new test macro with an active device array is presented for the mismatch characterization of npn bipolar transistors. The macro contains a CMOS circuit which serves for the selection of ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

When your car doesn’t start, often a low or dead battery is the culprit. Unfortunately, most vehicle owners do not check their battery until it fails. As preventative maintenance, the suggested best ...

The ULN2003 IC is an extremely versatile part, and with the help of [Hulk]’s deep dive, you might just get some new ideas about how to use this part in your own projects. Each of the seven outputs ...
