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 ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

The first transistor was successfully demonstrated at Bell Laboratories in Murray Hill, New Jersey, in 1947. This three-terminal device has spawned many of the electronics devices that make possible ...

How the first transistor evolved to meet new and emerging application demands as underlying structures transform and multi-die systems gained further adoption. How transistors have enabled the ...
