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 ...

On Dec. 16, 1947, the future began with the invention of the transistor. A lab notebook indicates that researchers at Bell Telephone Laboratories first got the thing to work on this day 75 years ago.

75 years ago this month, research scientists working at Bell Labs first created, then unveiled to the world a new device—the point contact transistor. Some call it the greatest invention of the 20th ...

This video explains what transistors are and how they function as electronic switches and amplifiers. As a core component of modern electronics, transistors control the flow of current and enable ...

The ever-shrinking features of transistors etched in silicon have always required pushing the cutting edge of manufacturing technology. The discovery of atomically thin materials like graphene and ...

At the December 2021 IEDM conference (a conference for people who design advanced semiconductors), IBM announced it was turning transistors on their heads to keep Moore’s Law scaling alive. The new ...
