With the E-MOSFET, VGS has to be, 'greater than VGS(th) to get any drain current at all. Therefore, when E-MOSFETs are biased, self-bias, current-source bias, and zero bias cannot be used because these forms of bias depend on the depletion mode of operation. This leaves gate bias, voltage-divider bias, and source bias as the means for biasing E-MOSFETs.
Fixed Bias,Self Bias, Forward Bias, Reverse Bias
the bias that we are better, smarter, and kinder than others
The Self Bias of the BJT is also called the voltage divider bias. It is called thus because it can stabilize the collector current, the base emitter voltage and the amplification factor.
1. stability factor s for voltage divider or self bias is less as compared to other biasing circuits . So this circuit is more stable and hence it is most commonly used. 2. this circuit is used where only moderate changes in ambient temperature are expected 3. the bias automatically adjusts to any variations in the circuit. by prerita agarwal
This arrangement is called SELF-BIAS. Now, if an increase of temperature causes an increase in collector current, the collector voltage (VC) will fall because of the increase of voltage produced across the load resistor (RL). ... One of the most widely used combination-bias systems is the voltage-divider type
Because for creating channal we need voltage at gate if there is no voltage at ate then VGS=0 this mean no amplificatiion can be done.
What? Bias is a one sided opinion
of course stability of self bias circuit is much greater than fixed bias circuit

The term self-enhancing bias is a complicated way of saying selfishness.
