Region of operation with both junctions forward biased:
The region of operation of a bipolar junction transistor (BJT) where both the emitter-base junction and the base-collector junction are forward biased is known as the saturation region.
Explanation:
- In the saturation region, the BJT acts as a closed switch, allowing a significant amount of current to flow from the collector to the emitter.
- The forward bias on both junctions causes the transistor to conduct heavily, resulting in minimal resistance between the collector and the emitter.
- The BJT operates in saturation when it is fully turned on and maximum current flows through it.
- In this region, the transistor operates at its minimum collector-emitter voltage and maximum collector current.
Significance:
- Saturation region is important in applications where the transistor needs to act as a closed switch, allowing maximum current flow.
- It is used in digital circuits, amplification stages, and in applications where the transistor needs to be in its most conducting state.
In summary, the saturation region of a BJT is where both junctions are forward biased, allowing maximum current flow from the collector to the emitter.
