Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
what is the Primary function of the common collector amplifier?
current gain
What are the disadvantages of using common emitter amplifier?
Disadvantages of CE amplifier:1. It has a high output resistance.2. It responds poorly to high frequencies.3. It has high thermal instabilities.4. It's voltage gain is very unstable.
A NPN transistor connected in common base mode has a current gain of 0.98 if it is now connected in common emitter mode what is the current gain?
The current gain in CE mode called as beta (ß) Tha current gain in CB mode called as alpha (A) ß= A/(1-A) =0.98/(1-0.98) =49 the current gain is 49 in CE mode
Is preteen weight gain common?
Preteen weight gain is common if your going through a growth spurt
Why is common emitter is greater than common collector?
Common-emitter gives more voltage gain because a common-collector amplifier has a voltage gain of 1. But a common-collector can have a power gain because the input impedance is much more than the output impedance.
What is CMRR?
CMRR is common mode rejection ratio. it is the ratio of Differential gain to common mode gain. CMRR=Ad/Ac
What is the role of insulin in weight gain?
Weight Gain Is a common side effect of Insulin
What is the voltage gain of common collector?
unity
What is the maxium current gain of common base amplifier?
If Beta is infinite, then the current gain will be unity.
Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.
What is the advantage of common emitter amplifier?
Itamplifiesthe gain
What is the alpha beta teta of a bipolar junction transistor?
alpha is the common base current gain = Ic/Ie.beta is the common emitter current gain = Ic/Ib.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
what is the Primary function of the common collector amplifier?
current gain
