The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

Bipolar Junction Transistors (BJTs): These were the earliest transistors (including the original 1947 point-contact device and later junction transistors). BJTs are made of three alternating ...

One of the semiconductor devices built in almost all electronic devices such as televisions, mobile phones, and PCs is "A transistor"is. Although I have heard of the name, actually it is not generally ...

Transistors are the magical electronic components that make your computer, smartphone and virtually every other gadget on the planet function—but how the hell do they work? One word: semiconductors.

Small electronic components "A transistor"Hundreds of millions of people are used in smartphones and PCs, which are indispensable to many people, as well as running a train, shedding music from ...

THANKS to the exponential power of Moore’s law, the electronic components that run modern computers vastly outnumber all the leaves on the Earth’s trees. Chris Mack, a chipmaking expert, working from ...

Researchers in Stuttgart have made a 6bit DAC using organic semiconductors, claiming that it is “1,000 times faster and 30 times smaller than the currently fastest 6-bit DAC in organics”. The team, ...
