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 ...

The most recent installment of [Dino Segovis’] Hack a Week covers the construction of a simple NPN transistor audio preamp. Some time ago, he built a small audio amplifier using an LM386 which worked ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Electronic components built from single molecules using chemical synthesis could pave the way for smaller, faster and more green and sustainable electronic devices. Now for the first time, a ...

Researchers have built electromechanical switches to replace transistors in high-heat computing. Researchers at Case Western Reserve University have taken the first step to building a computer capable ...

The very first transistor -- the foundational block which almost all of modern civilization was built from -- was created at AT&T's Bell Labs on December 23 1947. This first transistor was huge and ...
