The strict avalanche criterion (SAC) is a formalization of the avalanche effect. It is satisfied if, whenever a single input bit is complemented, each of the output bits changes with a 50% probability. The SAC builds on the concepts of completeness and avalanche and was introduced by Webster and Tavares in 1985. [4]
Avalanche breakdown (or the avalanche effect) is a phenomenon that can occur in both insulating and semiconducting materials. It is a form of electric current multiplication that can allow very large currents within materials which are otherwise good insulators. It is a type of electron avalanche.
The process can also be used to detect ionizing radiation by using the gas multiplication effect of the avalanche process. This is the ionisation mechanism of the Geiger–Müller tube and, to a limited extent, of the proportional counter [1] and is also used in spark chambers and other wire chambers.
Because the avalanche breakdown is uniform across the whole junction, the breakdown voltage is nearly constant with changing current [clarification needed] when compared to a non-avalanche diode. [1] The Zener diode exhibits an apparently similar effect in addition to Zener breakdown. Both effects are present in any such diode, but one usually ...
In electromagnetism, the Townsend discharge or Townsend avalanche is an ionisation process for gases where free electrons are accelerated by an electric field, collide with gas molecules, and consequently free additional electrons. Those electrons are in turn accelerated and free additional electrons.
The behavior of an avalanche depends on the structure of the snowpack, but that's only one ingredient. An avalanche requires all the wrong conditions at the wrong time. The angle of the mountain ...
Debt avalanche method. Putting $100 extra toward the 27.5% APR credit card would get you out of debt 31 months early and save you $3,408 in interest compared to making the minimum monthly payment.
Avalanche breakdown involves minority carrier electrons in the transition region being accelerated, by the electric field, to energies sufficient for freeing electron-hole pairs via collisions with bound electrons. The Zener and the avalanche effect may occur simultaneously or independently of one another.
