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 ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the ...

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.

If the resistor and capacitor values in your circuit are not properly calculated, then the output may be distorted and the amplitude may vary with time. If the resistor and capacitor values in your ...

This image taken with a transmission electron microscope shows the cross section of a new type of transistor shaped like a Christmas tree that was created by researchers at Purdue and Harvard ...

After dominating the electronics industry for decades, conventional silicon-based transistors are gradually approaching their ...

Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel ...

WEST LAFAYETTE, Ind. — A hacker can reproduce a circuit on a chip by discovering what key transistors are doing in a circuit – but not if the transistor “type” is undetectable. Purdue University ...
