Which stability is greater between self bias and fixed bias?
of course stability of self bias circuit is much greater than fixed bias circuit
What are the applications of fixed bias circuit?
low input impedance
What are the characteristics of fixed bias?
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.
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
What are the types of FET biasing circuit?
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias
Why emitter bias circuit is called self bias circuit?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
Advantages and disadvantage of self bias circuit?
the advantage of self bias circuit will be stable for greater range of amplitude signal than the fixed biased amplifier circuit the disadvantage is it only partially effective and therefore is only used where moderate changes in ambient temperature are expected
Why emitter bias circuit is called self bias?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
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
What are the different types of biasing?
Fixed Bias,Self Bias, Forward Bias, Reverse Bias
Why emitter bias is more stable than fixed bias?
negative feedback
