Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But ...

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 ...

The first transistor was successfully demonstrated at Bell Laboratories in Murray Hill, New Jersey, in 1947. This three-terminal device has spawned many of the electronics devices that make possible ...

Everything that's ever been made or used on a computer comes from transistors and circuits. Join Hank Green for a fascinating ...

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 ...

(Nanowerk Spotlight) Organic semiconductors have long held promise for enabling deformable electronic devices that can be manufactured at low cost and high volumes using printing techniques. However, ...
