Since the invention of microelectronic devices like transistors and the integrated circuit in the 1940s and ’50s, semiconductors have been the backbone of electronics. However, current microelectronic ...

A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...

Vacuum tubes disappeared from electronic products years ago. Yet there have been some lingering vacuum tube-based products in production. Vacuum tubes disappeared from electronic products years ago.

The project was designed using 6T9 vacuum tubes to build an amplifier device that operates in Ultra-Linear (UL) mode. The tube amplifier circuit works better in Ultra-Linear mode which used to operate ...

Most people associate vacuum tubes with a time when a single computer took up several rooms and "debugging" meant removing the insects stuck in the valves, but this technology may be in for a ...

The video explains the operation of the vacuum tube, specifically the triode, which is essential in modern communication devices like radios and telephones. It describes how a tungsten filament emits ...

Nothingness might not sound very useful. In fact, the opposite is the case because nothingness – in the form of a vacuum – has played a major role in the history of electronics. Until the invention of ...

For most of us, electronic technology comes in the form of solid state devices. Transistors, integrated circuits, microcontrollers. But for the first sixty years or so of the field existing, these ...

We’ve seen homemade x-ray devices and we’ve seen people making vacuum tubes at home. We’ve never seen anyone make their own x-ray tube, though, and it’s doubtful we’ll ever see the skill and ...

Vacuum contains nothing to interrupt charge flow, making it an ideal medium for electron conduction. Whereas charge flowing through a semiconducting channel will usually scatter, causing power loss ...
