Answer / soumya s nair
to fix the operating point at the middle of active region a
dc voltage is provided,ie it prevent the signal swing below
cut off.
Necesary of Biasing:
1)To fix the operating point at the middle of active region.
2)stabilize the collector current aganist temperature
varrions.
3)operating pont independant of transistor parameters

Transistor biasing is a special arrangemen tof transistor
which is made to operate it in active region of its
characteristics.

Answer / raju kumar
transistor biasing is three type
1) voltage divider biasing
2)emitter biasing
3)base bias
4)collector bias
in genral we use the voltage divider biasing .
biasing is necessary for transistor work like
emmiter base junction is in forward bias & collector base in
reverse bias so that transistor works in active resion.

Answer / linilb abu.ck
Q point of operating power is better.Q point of transistor
operating is very low distortion maximum signels or power
gain.Silicon for minium 0.7v germanium for minium 1v and it
is biasing of transistor.otherwords saturation point and
cutoff point works in the transistor is does not works the
amplifier
transistor biasing is three type
1) voltage divider biasing
2)emitter biasing
3)base bias
4)collector bias
in genral we use the voltage divider biasing .
biasing is necessary for transistor work like
emmiter base junction is in forward bias & collector base
in reverse bias so that transistor works in active region
that is Q point (sufficient working og transistor)

Answer / kazi mostafiz ahmed
simply it define biasing is a driver(voltage or current)
which is determined the transistor various operating point.

Answer / mukesh bramhane
The proper flow of zero signal collector current and maintainance of proper collector emitter voltage value during application of input signal.This process known as transistor biasing.
Is This Answer Correct ? | 13 Yes | 7 No |
Answer / john malik
biasing is required for the purpose of establishing proper operating conditions.and bias is separately applied with D.c supply
Is This Answer Correct ? | 3 Yes | 1 No |
Answer / chiru
to act transistor at active region and to bring Q point middle of active region we need transistor biasing
Is This Answer Correct ? | 0 Yes | 1 No |
Answer / praveen
We apply external DC supply to get desired operating (Q) this is called Biasing .
