"Biasing" applies to transistor amplifier circuits. Simple amplifier circuits can only amplify positive signals. Negative signals cause the amplifier to shut down. However, AC signals in general have both a positive and a negative part. To allow a transistor to amplify AC, we add a positive voltage to the AC signal. Then after it is amplified, we remove the positive voltage again.
The voltage, ac or dc on the base, compared to the emitter to cause operation of the transistor to conduct to the collector or to the emiiter in a NPN transistor.
What else can I help you with?
What is the voltage necessary to forward bias a transistor?
A silicon transistor needs about 0.65 v of forward bias on the base to begin to conduct.
How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
What is the relation between transistor operating region and bias conditions?
A: Depending on the load each linear operating region depends on the load and the correct bias insure it ANSWER: The relationship is strictly related to the bias Change the bias you change the operating region point of departure
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
Why a transistor can be operated in active region?
a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.
Why do you consider it necessary to bias transistor?
Why do you consider it neccessary to bias transistor?
What has the author Eric Wolfendale written?
Eric Wolfendale has written: 'Transistor bias tables (germanium)' 'Transistor bias tables'
What is the voltage necessary to forward bias a transistor?
A silicon transistor needs about 0.65 v of forward bias on the base to begin to conduct.
What is the difference between skepticism and bias?
Skepticism is uncertainty, while bias is prejudice.
What is the difference between the input bias current and the input offset current?
A: difference in bias current causes the other
What are the bias conditions base collector junctions for a transistor to operate as a switch?
Reverse bias
Why do you bias a field effect transistor?
we do bias field effect transistor because FET works if its Q point lies into active reason .If we bias FET ,the Q point lies in active reason
How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
How do you bias a 2N5777 photo transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
What are the factors that affect the bias stability of a transistor?
temperature
Why emitter bias circuit is called self bias?
The emitter bias circuit is called self-bias because the bias voltage across the emitter-resistor is based on the transistor's own characteristics. The bias voltage adjusts itself based on the varying collector current to stabilize the operating point of the transistor. It is a self-adjusting mechanism that helps maintain a stable bias point for the transistor.
What is the difference between a bias and a random error?
Bias is systematic error. Random error is not.
