What is self biasing a transistor?

if a transistor resistor is connected to the emmiter .


What is the biasing technique in transistor for it to be in active region?

For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.


Is transistor a linear or non linear device?

we will operate transistor mainly in 4 regions..namely active ,cutoff,saturation and pinch off region depending on the type of biasing. if it is under active region then transistor is a linear device.. linearity in the sense if the output is proportional to input then it is said to be linear.


Why bias a transistor?

A transistor begin to conduct if the Vbe is ~.6v following an exponential curve therefore non very linear. by biasing it is possible to achieve a linear portion of the load lines


Why voltage divider biasing circuit is the widely used biasing?

In a voltage -divider circuit method for biasing a transistor , we have two resistors R1 and R2 a DC supply voltage VCC and other components like collector resistor , emitter resistor are also present.here biasing is done by the help of voltage drop across the resistorsto understand the reason behind the extensive usage of voltage - divider method we need to know about the term stability.Stability factor of a transistor is defined as the ratio of amount of change in collector current to the amount of change in the same collector current with the base open(leakage current due to minority charge carriers)lesser the stability factor ------ that type of biasing is more desiredthe stability factor for voltage divider method is nearly equal to one.

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

What are the biasing roles of transistor?

A: Transistor to be effective as an linear amplifier it must be operated in its linear load range. The biasing scheme is to insure that the transistor is put in its linear/load range


What is emitter biasing?

Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.


What are operating point int transistor biasing?

A: An operating in biasing is determined by the transistor capabilities as a linear amplifier. Basically it is a bias to insure linear operation with the loading of the output


What is the Purpose of dc biasing in transistors?

in order to establish the Q-point of transistor


What is difference between transistor biasing and connection?

Transistor biasing is a function of implementing a DC support circuit that places the transistor in an electrical region that produces the desired output signal in relation to its input signal, according to its design specification. A transistor can be biased to create a linear amplified signal proportional to its input. Biasing can also place the transistor into an easily saturated condition to propagate clipped binary output relative to its input. Biasing refers to the component configuration designed around a specific transistor family. Connection refers to the simple function of making an electrical junction between two conductors.


What is meant by biasing and explain all the baises?

It means that a voltage is established between two of the three terminals of a transistor, to achieve the desired operation. Since with three terminals you can choose three different combinations of two terminals, there are three different types of biasing.The details vary, depending on the type of transistor used. Also, the details are quite involved. The Wikipedia has some introductory articles; for example the article on "Biasing", or on "Bipolar transistor biasing" if you want to know about biasing for this specific type of transistor.


Why CE transistor is more temperature senstive than CB transistor?

In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.


What is the purpose of dc biasing of transistor?

Why are 2 batteries needed for biasing a transistor?

They aren't, it can and is done just fine with one.
