Question
Which method of biasing is used for operating a transistor as an amplifier?
Advertisements
Solution 1
For use as an amplifier, the transistor should be inactive mode. Therefore, the emitter-base junction is forward biased and the collector-base junction is reverse biased. Also, an amplifier uses an emitter bias rather than a base bias.
Solution 2
For transistor operating as an amplifier, the emitter-base junction is forward biased while the collector-base junction is reverse biased.
