Devoting a whole chapter in a modern electronics text to the design and function of electron tubes may seem a bit...

For extremely high-frequency applications (above 1 GHz), the interelectrode capacitances and transit-time delays of...

In addition to performing tasks of amplification and switching, tubes can be designed to serve as display...

So far, we’ve explored tubes which are totally “evacuated” of all gas and vapor inside their glass envelopes,...

For bipolar junction transistors, the fundamental measure of amplification is the Beta ratio (β), defined as the ratio...

Similar in thought to the idea of the integrated circuit, tube designers tried integrating different tube functions...

Another strategy for addressing the problem of secondary electrons being attracted by the screen was the addition of a...

In the beam power tube, the basic four-element structure of the tetrode was maintained, but the grid and screen wires...

As the name suggests, the tetrode tube contains four elements: cathode (with the implicit filament, or “heater”),...

De Forest’s Audion tube came to be known as the triode tube because it had three elements: filament, grid, and plate...

Thomas Edison, that prolific American inventor, is often credited with the invention of the incandescent lamp. More...

An often neglected area of study in modern electronics is that of tubes, more precisely known as vacuum tubes or...
