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 ...

How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...

Why silk is being used for bio-compatible transistors. How the silk is transformed to develop the transistor function. The two types of operation provided by the silk-based transistor. Silicon and ...

We’re surrounded by transistors. They’re all around us. They’re in phones, car keys, microwaves, pacemakers and plenty more. The transistor is a revolutionary piece of technology that helped create ...
