Which of the following statements is correct regarding the input characteristics (IB vs VBE) of a common-emitter (CE) transistor configuration?
- 1In a CE configuration, the IB vs VBE plot is plotted at a constant emitter current (IE).
- 2The plot of IB vs VBE is strictly linear starting from zero.
- 3The input current (IB) decreases slightly with an increase in the reverse-biased collector-emitter voltage (VCE) due to the Early effect.✓
- 4Typically, the input current (IB) is in the range of up to 10 A, while the input voltage (VBE) is in the range of up to 5 V.
Correct answer
The input current (IB) decreases slightly with an increase in the reverse-biased collector-emitter voltage (VCE) due to the Early effect.
