As channel length decreases, the barrier φ B to be surmounted by an electron from the source on its way to the drain reduces. Drain-induced barrier lowering (DIBL) is a short-channel effect in MOSFETs referring originally to a reduction of threshold voltage of the transistor at higher drain voltages.
To combat drain-induced barrier lowering (DIBL), MOSFET substrate near source and drain region are heavily doped (p+ in case of NMOS and n+ in case of PMOS) to reduce the width of the depletion region in the vicinity of source/substrate and drain/substrate junctions (called halo doping to describe the limitation of this heavy doping to the ...
In electronics, short-channel effects occur in MOSFETs in which the channel length is comparable to the depletion layer widths of the source and drain junctions. These effects include, in particular, drain-induced barrier lowering, velocity saturation, quantum confinement and hot carrier degradation. [1] [2]
Subthreshold leakage in an nFET. Subthreshold conduction or subthreshold leakage or subthreshold drain current is the current between the source and drain of a MOSFET when the transistor is in subthreshold region, or weak-inversion region, that is, for gate-to-source voltages below the threshold voltage.
Gate-induced drain leakage, a leakage mechanism in MOSFETs due to large field effect in the drain junction Generic Interface Definition Language , an extension to CORBA IDL Topics referred to by the same term
Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
For the SIT, the breakdown voltage is not limited by the surface breakdown between gate and drain, allowing it to operate at a very high current and voltage. The SIT has a current-voltage characteristic similar to a vacuum tube triode and it was therefore used in high-end audio products, including power amplifiers from Sony in the second half ...
