Question
The current gain generated from these devices can be hugely increased by connecting two together to form a Darlington pair. For 10 points each:
[10m] Name these devices that come in PNP and NPN types, depending on how the collector, base, and emitter are doped. They’re contrasted with similar “metal–oxide–semiconductor”-based devices.
ANSWER: bipolar junction transistors [or BJTs; prompt on transistors]
[10e] BJTs can be treated as two of these devices connected together such that minority carriers travel through the base. These devices allow electric current to flow in only one direction and come in a “light-emitting” type.
ANSWER: diodes [accept light-emitting diodes; prompt on LEDs]
[10h] BJTs can be characterized by their Early voltage and this parameter, which is often about 50. This parameter equals the ratio between the collector and base current.
ANSWER: beta [or common-emitter current gain; prompt on partial]
