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 ...

How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...

Transistors are the magical electronic components that make your computer, smartphone and virtually every other gadget on the planet function—but how the hell do they work? One word: semiconductors.

Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals? The word "transitor" has become almost invisible ...

I was digging around in the LM311 (and LM111, LM211) comparator data sheet, and came across this unusual voltage reference (diag right). It consists of an npn cascsode pair of transistors, the top one ...

[Dr. Cockroach]’s goal was to build a four-bit computer out of recycled and repurposed junk. The resulting computer, called IO, consists of a single 555, around 230 PNP and NPN transistors, 230 diodes ...
