![]() This can be achieved using a process known as Biasing.īiasing is very important in amplifier design as it establishes the correct operating point of the transistor amplifier ready to receive signals, thereby reducing any distortion to the output signal.Īlso, the use of a static or DC load line drawn onto the output characteristics curves of an amplifier allows us to see all the possible operating points of the transistor from fully “ON” to fully “OFF”, and to which the quiescent operating point or Q-point of the amplifier can be found. Then some way of “presetting” a common emitter amplifier circuit configuration is required so that the transistor can operate between these two maximum or peak values. Transistor amplifier’s amplify an AC input signals that alternates between some positive value and a corresponding negative value. ![]()
