Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
FET's (field effect transistors) are unipolar devices because unlike BJT's that use both electron and hole current, they operate only with one type of charge carrier. BJT is a current-controlled device; that is the base current controls the amount of collector current. FET is a voltage-controlled device, where voltave between two of the terminals (gate and source) controls the current through the device. BJT's have a low input impedance ( ~1k -3k ohms), while FET's have a very high input impedance (~10^11 ohms). Consequently FET's have a lower power consumption. BJT's produce more noise than FET's . FET's have a slower switching speed . BJT's are subject to thermal runway while FET's are immune to this problem. BJT's have a higher cutoff frequencey and a higher maximum current then FET's. FET's are easy to fabricate in large scale and have higher element density the BJT's.
Bipolar dc involves both majority carrier and minority carriers for conduction while unipolar requires only majority carriers or minority carriers during conduction. point of view based on electronics devices.
There are two different winding configurations for stepper motors. A unipolar stepper motor has one winding coil and a center tap which is activated for proper frequency. The bipolar stepper motor is more complex since the winding motion must be reversed to get the proper frequency.
A device optioned for B8ZS (Bipolar 8-Zero Substitution) inserts a bipolar violation into any frame containing 8 zeroes in a specific sequence during transmission of that frame. The device at the receiving end simply looks for that specific sequence and changes the bit sequence in that frame back to 8 zeros.
Bipolar junction transistor(BJT)
ic made from bjt is known as bipolar ic
Unless it is some leet speak term I am not aware of, BJTstands for Bipolar Junction Transistor or (less common) Business Japanese Proficiency Test.
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
bjt is bipolar device whr fet is unipolar....fet is input resistance thts y fet gain is less compared to bjt..... The applications that will prefer bipolar junction transistors to field effect transistors are applications that require fast switching.
If you have questions about Bipolar Junction Transistors (BJT), there are a small handful of websites. Indiabix, All About Circuits, and Research Gate are some places you can find information.
IGBT and BJT are bipolar devices as the name suggest. Meaning of bipolar device both electrons and holes leads to current unlike FET where either electron or hole causes current.
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
Bipolar junction transistors has two junctions base emitter junction, base collector junction. Accordingly there are four different regions of operation in which either of the two junctions are forward biased reverse biased or both. But the BJT can be effectively operated in there different modes according to the external bias voltage applied at each junction. i.e. Transistor in active region, saturation and cutoff. The other region of operation of BJT is called as inverse active region.
TTL stands for "transistor-transistor logic" and consists of using BJT's ("bipolar junction transistors") to conduct the logic for the circuit.
