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 ...

Digital transistors—assembled by the billions in today's computer chips—act as near-perfect electronic switches. In the "on" position, achieved when an above-threshold voltage is applied to the device ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

Transistors that can change properties are important elements in the development of tomorrow's semiconductors. With standard transistors approaching the limit for how small they can be, having more ...

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 ...

In a shining example of the inexorable march of technology, IBM has unveiled new semiconductor chips with the smallest transistors ever made. The new 2-nanometer (nm) tech allows the company to cram a ...
