WebHaving both polarities of transistors allows for more flexibility in how amplifier sages can be combined and can make biasing easier as well. For example, a complementary cascade amplifier is shown in figure 10.1.4. The second common emitter stage uses a PNP transistor. The gain calculation procedure is the same as the all-NPN cascade. WebOct 25, 2024 · A transistor functions as an amplifier by increasing the power of a weak signal. The emitter-base junction is kept in a forward-biased condition by the DC bias voltage that is provided to it. No matter how the signal is polarized, this forward bias remains. Using a transistor as an amplifier is seen in the image above.
WebFigure 1: Basic NPN common collector circuit (neglecting biasing details). In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as …
