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 ...

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 late 1950s and early 1960s saw perhaps the most dramatic change ever to hit electrical engineering. When transistors came along, many engineers needed to quickly learn how they worked and how to ...

Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals? The word "transitor" has become almost invisible ...

Learn how to build a DIY portable speaker using a car speaker, cardboard, and basic electronic components. This step-by-step ...

Saswato R. Das writes about physics and astronomy. A little electronic device that triggered one of the most dramatic technological explosions in history turns 60 on Sunday. The humble transistor and ...

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 new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires is closer to reality after a key discovery by researchers at IBM, ...

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 ...
