Discuss The Need For Biasing The Transistor?
For normal operation, base-emitter junction should be forward biased and the collector-base junction reverse biased. The amount of bias required is significant for the establishment of the operating or the Q-point which is dictated by the mode of operation desired. In case the transistor is not biased properly, it would: Work efficiently Produce distortion in the output signal With the change in transistor parameters or temperature rise, the operating point may shift and the amplifier output will be unstable.
