Some articles on base, region, base region, regions:

Types - Bipolar Junction Transistor
... This construction produces two p-n junctions a base–emitter junction and a base–collector junction, separated by a thin region of semiconductor known as the base region (tw ... corresponding to the three layers of semiconductor – an emitter, a base, and a collector ... and collector are controllable by a relatively small base current." In an NPN transistor operating in the active region, the emitter-base junction is forward biased (electrons and electron holes recombine at the ...
Junction Transistor - Introduction - Voltage, Current, and Charge Control
... current can be viewed as being controlled by the base–emitter current (current control), or by the base–emitter voltage (voltage control) ... These views are related by the current–voltage relation of the base–emitter junction, which is just the usual exponential current–voltage curve of a p-n junction (diode) ... for collector current is the amount of minority carriers in the base region ...
Junction Transistor - Introduction
... and NPN based on the doping types of the three main terminal regions ... An NPN transistor comprises two semiconductor junctions that share a thin p-doped anode region, and a PNP transistor comprises two semiconductor ... In typical operation, the base–emitter junction is forward biased, which means that the p-doped side of the junction is at a more positive potential than the n-doped side, and the ...
Distributed Element Model - Applications - High Frequency Transistors
... Another example of the use of distributed elements is in the modelling of the base region of a bipolar junction transistor at high frequencies ... The analysis of charge carriers crossing the base region is not accurate when the base region is simply treated as a lumped element ... transmission line model which includes distributed bulk resistance of the base material and distributed capacitance to the substrate ...

Famous quotes containing the words region and/or base:

    I was with Hercules and Cadmus once,
    When in a wood of Crete they bayed the bear
    With hounds of Sparta: never did I hear
    Such gallant chiding; for besides the groves,
    The skies, the fountains, every region near
    Seemed all one mutual cry. I never heard
    So musical a discord, such sweet thunder.
    William Shakespeare (1564–1616)

    I have always heard, Sancho, that doing good to base fellows is like throwing water into the sea.
    Miguel De Cervantes (1547–1616)
