Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...

Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper ...

The telephone company had problems with vacuum tubes, too, and hoped to find something else to use for switching telephone calls. The idea of somehow using semiconductors (solid materials such as ...

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 first digital use of the transistor for consumers was in a calculator,” says Rick Bensene, curator of the Old Calculator Web Museum. Our series on the birth of the transistor — and with it, the ...

A reconfigurable transistor can run AI processes using 100 times less electricity than the standard transistors found in silicon-based chips. It could help spur development of a new generation of ...

A University at Buffalo team has proposed a new form of power MOSFET transistor that can handle incredibly high voltages with minimal thickness, heralding an efficiency increase in the power ...
