What is the difference between linear and saturation regions in field effect transistor?
In the linear region, the transistor has an almost linear I versus V curve, which means that as you increase drain-source voltage, current changes proportionally, e.g. to a loose approximation, the FET behaves like a resistor, whose resistance is set by the gate-source voltage. In the saturation region, the I vs V curve looks like a horizontal line (almost) so it acts like more like a switch (neither of these analogies is exact, but they give the general idea).

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.
What separates the three regions in a BJT?
Two junctions namely emitter-base junction and collector-base junction separates regions in a transistor.
What are the operating regions of transistors and explain it?
There are three operating regions in transistor...(Transfer-Resistor)1)cutoff region2)Active region3)Saturation regionActive region:It is the central region where there are curves and where slope is taken.it is the region where emitter-base is forward biased and collector-base is reversed bias.Cutoff region:It is the region which lies below the curves. it is the region where the transistor is in OFF state.in this region both emitter-base and collector-base is reversed bias(i.e no sufficient voltage is applied so that the voltage does not break the DEPLETION region).Saturation region:It is the region situated to near the active region near Y-axis.It is the region in which the both emitter-base and collector-base is forward biased.Based on application the transistor is decided where to lie.for example transistors are made to lie in active region to make it as amplifier.when transistors are used as switch it is made to lie in saturation region(when switch is made as ON) and cut-off region(when switch is made as OFF).....Thanks guys for reading this. please forgive me if there are any mistakes....ANSWER: In actuality there is only one REGION The other regions are not operating regions but rather states. An operating region on a transistor is set up during design of an amplifier to transfer maximum undirstorted power to the load. This design is called BIAS
What is transistor action?
The transistor has three regions, emitter,base and collector. The base is much thinner than the emitter while the collector is wider than both. However for the sake of convenience the emitter and collector are usually shown to be of equal size. The transistor has two pn junctions that means it is like two diodes. The junction between emitter and base may be called emitter-base diode or simply the emitter diode.The junction between base and collector may be called collector-base diode or simply collector diode. The emitter diode is always forward biased and the collector diode is always reverse biased.
Why is the collector region in the transistor the largest?
The collector is so named because it collects electrons from base. The collector is the largest of the three regions, thus it must dissipate more heat than the emitter or base. that is why it has a larger area.
Why biasing a transistor?
We bias transistors in order to determine the modes of operation ( that is whether the transistor is operating in the active cut off or the saturation regions).
What is a closed transition switch?
The transistor have three regions namely cut off,active,and saturation.When the switch is in saturation region then it is called the transition on or we can say the switch is closed
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.
What are the uses of transistor in circuits?
Basically each and every amplifier circuit is made up of coupling or use of transistors. The amplifier amplifies the signals because transistor makes either voltage or current to rise as a result of either of it's regions of operation i.e. open circuit(cut off region) or short circuit (saturation region) Both the operation regions are not required continuously. Hecne the transistor works in either saturation or cut off regions only when emitter-base junction is forward biased, which can be applied as per requirement. APPLICATIONS OF TRANSISTOR AND HENCE AMPLIFIERS ARE : OSCILLATORS, LOUD-SPEAKERS, POWER AMPLIFIERS, VOLTAGE AMPLIFIERS, CURRENT AMPLIFIERS, ANALOG TO DIGITAL CONVERTER, DIGITAL TO ANALOG CONVERTERS
Number of depletion regions in transistor?
two The transistor has one depletion layer.
How you find the difference between 2 regions?
measure them
What colonial regions used Protestant government?
Well the difference between the three colonial regions is.......
What are the operating regions of transistors?
operating region of the transistor is the area of the voltage and an electronic configuration in which a transistor can work with its full efficiency. In that operating region transistor can be used easily what above said by harsh is correct...the following may help u further... Based on application the transistor is decided where to lie. for example transistors are made to lie in active region to make it as amplifier. when transistors are used as switch it is made to lie in saturation region(when switch is made as ON) and cut-off region(when switch is made as OFF).....
What is the difference between intergenic and intragenic regions in a genome?
Intergenic regions are stretches of DNA located between genes, while intragenic regions are parts of a gene itself.
What separates the three regions in a BJT?
Two junctions namely emitter-base junction and collector-base junction separates regions in a transistor.
How is a potential difference achieved?
by creating two regions one region with more number of electrons than the other we can obtain potential difference between the two regions.
How does specialization affect trades between regions?
it affect by the difference mrs petras
