Dynatron oscillator — A dynatron oscillator is an electronic circuit that uses negative resistance to keep an LC tank circuit oscillating. In theory, if an ideal capacitor is connected in parallel with an ideal inductor, they form a resonant circuit that, once it… … Wikipedia
Dynatron — For the brand, see Dynatron Radio Ltd The dedicated dynatron vacuum tube was invented by Albert Hull in 1918 [http://ieee.cincinnati.fuse.net/newsletters/200401.pdf] . It has three electrodes: a thermionic cathode, a perforated anode, and a… … Wikipedia
Negative resistance — is a property of some electric circuits where an increase in the current entering a port results in a decreased voltage across the same port. This is in contrast to a simple ohmic resistor, which exhibits an increase in voltage under the same… … Wikipedia
Vacuum tube — This article is about the electronic device. For experiments in an evacuated pipe, see free fall. For the transport system, see pneumatic tube. Modern vacuum tubes, mostly miniature style In electronics, a vacuum tube, electron tube (in North… … Wikipedia
Tetrode — A tetrode is an electronic device having four active electrodes. The term most commonly applies to a two grid vacuum tube. It has the three electrodes of a triode and an additional screen grid which significantly changes its behaviour. Grids The… … Wikipedia
Secondary emission — is a phenomenon where additional electrons, called secondary electrons, are emitted from the surface of a material when an incident particle (often, charged particle such as electron or ion) impacts the material with sufficient energy. The number … Wikipedia
Screen grid — The screen grid is a grid introduced into a vacuum tube (thermionic valve) to greatly reduce the capacitance between two other parts of the electrode structure.In its simplest form, a screen grid is placed between the control grid and anode or… … Wikipedia
Suppressor grid — A suppressor grid is a grid used in a thermionic valve (also called vacuum tube) to suppress secondary emission. A suppressor grid is also called the antidynatron grid, as it helps to reduce the dynatron effect. Placement In its simplest form, a… … Wikipedia
Tunnel diode — A tunnel diode or Esaki diode is a type of semiconductor diode which is capable of very fast operation, well into the microwave frequency region, by using quantum mechanical effects. It was invented in 1958 by Leo Esaki, who in 1973 received the… … Wikipedia
