Among semiconductors, the muting transistor and its audio application is perhaps the most obscure and poorly understood of all. There is extremely little information on this subject available on the ...

In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil contacts ...

Process devices operate when an input level, such as voltage, reaches the required value for the device to operate. The transistor is on, when the input voltage is greater than or equal to \(0.7 V\).

Tesla coils are one of those builds that capture the interest of almost anybody passing by. For the naïve constructor, they look simple enough, but they can be finicky beasts—beasts that can bite if ...

It was late afternoon at a conference for the Institute of Radio Engineers. Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at ...

Researchers have developed the first transistor made of wood. Their study paves the way for further development of wood-based electronics and control of electronic plants. Researchers at Linköping ...

The ever-shrinking features of transistors etched in silicon have always required pushing the cutting edge of manufacturing technology. The discovery of atomically thin materials like graphene and ...

The new type of transistor, known as the "cryo-CMOS transistor," is optimized to operate at temperatures under 1 K and emit near-zero heat. When you purchase through links on our site, we may earn an ...

Texas Instruments announced plans for the Regency TR-1, the first transistor radio to be commercially sold, on October 18, 1954. The move was a major one in tech history that would help propel ...
