This tester is primarily meant to test bipolar transistors. It can indicate the type of the transistor as well as identify its base, collector and emitter pins. The circuit is very simple. The ...

The common-emitter configuration (Figure 1a) is the only one in which the input and output are out of phase. For efficient operation at high frequencies, it is crucial to minimize the series ...

Amazon has been getting creepier and creepier lately with their recommendations. Every time I log in, I’m presented with a list of new Blinky LEDs, Raspberry Pi accessories, Arduino shields, and the ...

Graphene’s potential was recognized earlier this month when those who first studied it in the lab won the 2010 Nobel Prize in Physics. But researchers are just beginning to figure out how to take ...

Organic semiconductor technology relies on carbon-based materials, and it is known as one of the promising key technologies for realizing large-area and low-cost electronics. Owing to recent intensive ...

Scientists have achieved a milestone in creating a building block for the future of wireless devices. Researchers have announced the first integrated circuit fabricated from wafer-size graphene, and ...

Researchers previously reported a self-aligned technique for making graphene transistors with unparalleled speed, but scalability was a question. The team now uses a dielectrophoresis assembly ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .
