Biasing of Transistor:

Need of Biasing:

• The proper flow of zero signal collector current and the maintenance of proper collector emitter voltage during the passage of signal is called the transistor biasing.
• It is essential for faithful amplification.

If the transistor is not biased properly, It would be

• Work inefficiently
•  Produce distortion in the output signal.

Keep in Mind:

• Input side should be in Forward Biased
• Output side should be in Reverse Biased
• Base Resistance R_B >>R_C

There are some transistor biasing circuits:

1. Fixed Bias
2. Potential Divider Bias
3. Two Supply Emitter Bias
4. Emitter – Feedback Bias
5. Collector Feedback Bias
6. Collector – and Emitter – Feedback Bias
