If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

A look at the dual bipolar transistor zener clamp circuit, and it's usefulness as a fast low leakage overload clamp. The ...

A detailed teardown of the Type-75 Geiger counter reveals the J405 tube, energy compensation shroud, and a clever ...

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell ...

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 ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...
