The vacuum tubes used as power amplifiers in microwave systems may be on their way out following the development by a research team from US-based Agere Systems of a solid-state microtriode that can be ...

And now a page from our "Sunday Morning" Almanac: November 16th, 1904, 110 years ago today . . . the birthday of an invention heard 'round the world. For that was the day the British inventor John ...

It’s best to admit upfront that vacuum tubes can be baffling to some of the younger generation of engineers. Yes, we get how electron flow from cathode to anode can be controlled with a grid, and how ...

Moore’s Law is under threat. In the battle between chip designers and the laws of physics, it’s beginning to look like it won’t be long before it’s impossible to double the number of transistors on ...

EASTHAMPTON — In a world ruled by the microchip, David Mell’s customers at Viva Tubes crave the soft electric hum and warm audio tone of the old-fashioned analog vacuum tube. Tubes — simple devices ...

Remember those old-timey room-sized vacuum-tube-powered computers with less processing power than your smartphone? That tech might be making a comeback, thanks to work from scientists from UC San ...

One of the topics we've covered multiple times at ExtremeTech is the difficulty of continuing to scale semiconductor technology, and the related problem of improving chip performance without ...

AT a meeting of the Philosophical Society of Glasgow on December 22, 1880, I gave a very brief preliminary account of some experiments that I have been making, along with Sir William Thomson, with ...
