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 ...

Talking about vacuum tubes in 2025 might seem like talking about the role of buggy whips in today’s transportation world; but that’s not the case. There’s no denying that these devices—called vacuum ...

The triode is one of the simplest kinds of vacuum tubes. Inside its evacuated glass envelope, the triode really is just a few bits of wire and metal. Triodes are able to amplify signals simply by ...

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 ...

The triode vacuum tube might be nearly obsolete today, but it was a technology critical to making radio practical over 100 years ago. [Kathy] has put together a video that tells the story and explains ...

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 ...

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 ...

Prior to Bell Labs’ first working transistor in 1947, which ushered in the advent of semiconductor technology and the computer age, every long-distance telephone call, radio and television broadcast, ...

SōLIS, an audio brand that has been around for four decades, is constantly evolving. Many of its current offerings pair with Google Home and Chromecast devices and it made a nice showing at CES with ...

Back to the future: LG Electronics has seemingly adopted a retro design language heading into CES. The South Korean tech giant recently debuted a new 4K smart projector that looks like an old-school ...
