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.

The transistor, invented at Bell Labs in 1947, replaced bulky vacuum tubes and enabled the miniaturization revolution that created modern electronics. The transistor stands as one of the most ...

Recently in material science news from China we hear that [Hailin Peng] and his team at Peking University just made the world’s fastest transistor and it’s not made of silicon. Before we tell you ...

The 2D transistor’s design looks like a series of interwoven bridges. Photo: Peking University/modified by ZME Science. At Peking University, a group of Chinese scientists may have just turned the ...

A bipolar junction transistor (BJT) is a device that can amplify signals thanks to its two p-n junctions and three terminals: base, collector and emitter. This device is operated by current. At the ...

A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...
