I know nothing about fixed bias,So I try this web to know but this web address fail to answer my question.
What_is_fixed_bias_circuit
this is a fake web it can't help anyone

negative feedback
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias

To overcome the disadvantages of fixed bias configuration, one can implement voltage divider biasing, which provides better stability against variations in transistor parameters and temperature changes. Additionally, using feedback mechanisms, such as emitter feedback bias, can enhance linearity and improve thermal stability. Incorporating a bypass capacitor may also help maintain gain while improving AC performance. Overall, these methods can significantly mitigate the limitations associated with fixed bias setups.
common emitter using fixed bias
because we are not varying the biasing voltage
because we are not varying the biasing voltage
of course stability of self bias circuit is much greater than fixed bias circuit
It is a bias of a fixed voltage supplied by a separate low-power bias supply. Early radios used a 9 v tapped bias battery. In some amplifiers fixed bias can be dispensed with and the bias voltage is derived from one of the currents in the circuit.
Fixed Bias,Self Bias, Forward Bias, Reverse Bias
negative feedback
This is called bias or stereotyping. Bias occurs when there is a preference or prejudice in favor of or against one thing, person, or group. Stereotyping is a fixed, oversimplified image or idea of a particular type of person or thing.
