Feb 24, 2012 · When transistors operate in the active region, they act as amplifiers, increasing the strength of the input signal without significant alteration. This behavior is due to the movement of charge carriers.
Feb 27, 2024 · Learn how transistors can be used as amplifiers to increase weak signals without changing their frequency or form. Explore the common emitter configuration, the characteristics, the performance, and the working of transistor amplifiers.
A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. This forward bias is maintained regardless of the polarity of the signal.
