The circuit is a simple one, and a classic. The spring from a ballpoint pen is soldered to the base of a BC547 transistor, and when held close enough to a conductor carrying AC power, a current is ...

But banish any visions you may have of transistors just nine or ten atoms wide. The transistors in the “20 A ” architecture, ...

If you want to control it from a 3.3 V MCU that can’t handle the high-side voltage on its pins, you can add a NPN transistor section as shown – this inverts the logic, making it into a more ...

The transistor is considered to be one of the most important inventions of the 20 th century because of its abundant use in most modern circuits and electronic systems. NPN and PNP are the two ...

and Field Effect Transistors (FETs). BJTs are controlled by current, while FETs are controlled by voltage. Within these categories, there are further subdivisions such as NPN and PNP BJTs and ...

As such, there are two basic configurations for BJTs: the NPN-type and the PNP-type. The current and voltage polarities for a PNP transistor are opposite that of a NPN transistor, but the two ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few optical transistors or logic devices possess them 3.

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...
