In the transfer characteristics (Output Voltage Vo vs Input Voltage Vi) of a base-biased common-emitter (CE) transistor, which of the following statements is false?
- 1At Vi = 0.4 V, the transistor is in the active state.✓
- 2At Vi = 1 V, it can be used as an amplifier.
- 3At Vi = 0.5 V, it is in the cut-off region and can be used as a switch turned off.
- 4At Vi = 2.5 V, it is in the saturation region and can be used as a switch turned on.
Correct answer
At Vi = 0.4 V, the transistor is in the active state.
