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 ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

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 ...

New chips based on the 22-nanometer designs will run at a lower voltage and with lower power leakage, in an effort to improve both performance and energy efficiency. Erica Ogg is a CNET News reporter ...

The transistor laser, invented by scientists at the University of Illinois at Urbana-Champaign, has been full of surprises. Researchers recently coaxed the device to reveal fundamental properties of ...

the scaling of silicon-based metal-oxide-semiconductor field-effect transistors (Si MOSFETs) and evolution of novel structure transistors in accordance with Moore’s Law, especially for modern ...

Several foundries continue to develop new processes based on next-generation gate-all-around transistors, including more advanced high-mobility versions, but bringing these technologies into ...

Diodes has introduced a series of low saturation npn and pnp bipolar transistors optimised for automotive power switching and control. “With BVceo up to 100V, continuous current to 10A – and 20A peak ...

The structure it has invented is called Tri-Gate and will be first used in chips manufactured using the 22-nanometre process, nicknamed Ivy Bridge. Continuing along the path of Moore's Law would have ...
