Download Solution PDFHow are the junctions biased in a transistor when operating in the saturation region?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFA transistor can be operated in one of the three modes:
1) Active Region
2) Saturation Region
3) Cut-off Region
The biasing for different mode of operation is as shown in the table:
|
Mode |
Emitter -base Junction |
Collector-Base Junction |
|
Cut off |
Reverse |
Reverse |
|
Active |
Forward |

|
Reverse Active |
Reverse |
Forward |
|
Saturation |

∴ For a transistor operating in the saturation region, both the junctions need to be forward bias.
