Discuss The Need For Biasing The Transistor?

Answer»

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.
