engineering recuitment GATE ECE 2023-24 Test Series Electronic Devices Bipolar Junction Transistor Basic Principle of Operation
For a narrow base PNP BJT, the excess minority carrier concentrations (ΔnE for emitter, ΔpB for base, ΔnC for collector) normalized to equilibrium minority carrier concentrations (nE0 for emitter, pB0 for base, nC0 for collector) in the quasi-neutral emitter, base and collector regions are shown below. Which one of the following biasing modes is the transistor operating in?
1
Forward active
2
Saturation
3
Inverse active
4
Cutoff
