What are the different types of biasing?
Fixed Bias,Self Bias, Forward Bias, Reverse Bias
What are the applications of fixed bias amplifier circuit?
low input impedance
Why fixed bias circuit is called so?
because we are not varying the biasing voltage
Advantage and disadvantage of fixed bias circuit?
Advantages: 1) This is a simple circuit which uses very few components 2) The operating point can be selected anywhere in the active region of the characteristics by simply changing the value of Rb.Thus,it provides maximum flexibility in the design. Disadvantages: 1) Thermal stability is not provided in the circuit.Thus Q-point is not maintained. Ic = β Ib + Ico Ic = β Ib 2) Since Ib is already fixed,Ic depends on β which changes unit to unit and shifts the Q-point.Thus the stability is very poor.
What is the advantages of emitter bias configurations over fixed bias configurations?
One of the main advantages of using the emitter bias configuration has to do with the Q-points. With changes in the current gain, those Q-points don't change. Since the collector current accounts for 99% of the emitter current, we come up with a 1% margin of error, much better than the 5% we can get with the fixed-base bias configuration and Ic and Vce do not fluctuate as well.
Why fixed bias is called fixed bias?
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_circuitthis is a fake web it can't help anyoneSudip
Which stability is greater between self bias and fixed bias?
of course stability of self bias circuit is much greater than fixed bias circuit
