Temperature (assumed) compensation in a transistor is when you limit gain using resistors so that gain is dependent on resistor ratio instead of on hFe.
As an example, in a common emitter, class A, configuration, with the emitter grounded, the gain is hFe. Problem is that hFe varies from device to device, and it is temperature sensistive, having a positive temperature coefficient, making thermal runaway a very real problem.
You can compensate for this with an emitter resistor. In combination with the collector resistor, gain is collector resistance divided by emitter resistance, or hFe, whichever is less. If you make sure that hFe is always greater than this ratio, then the gain will be stable and predictable.

What is meant by transistor AD162?
An AS162 transistor is a type of PNP transistor commonly made of germanium. This is an older kind of transistor that was often found in power amplification circuits.
What is meant by logical?
TTL stands for "transistor-transistor logic" and consists of using BJT's ("bipolar junction transistors") to conduct the logic for the circuit.
What is meant by ttl logic?
TTL stands for "transistor-transistor logic" and consists of using BJT's ("bipolar junction transistors") to conduct the logic for the circuit.
What is meant by saying at what current is transistor biased?
The saying "at what current is transistor biased" means to ask the current through the transistor when there is no signal present. Typically, a transistor is biased at the center of its linear region, so as to minimize distortion. This, of course, depends on whether or not the transistor is AC or DC coupled, and where the clipping points might be.
What is meant by BC548 for a transistor?
It doesn't "mean" anything. It's simply the identification, the type number.
What compensation technique is better than other techniques in transistor biasing?
That would depend on your application. If there was a singke best way, that would be the only method used.
What is Si transistor?
A silicon transistor is a transistor made of silicon.
Is active is a cutoff region of transistor?
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
What is the purpose of the Unijunction Transistor?
A Unijunction Transistor is a transistor that acts solely as a switch.

Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
