What applications would prefer the bipolar junction transistors over the field effect transistor?
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.
What are the uses of BJT?
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.
Transistors can be either what or what?
either field effect (JFET, MOSFET) or junction (BJT) or point contact (usually considered obsolete)either small signal or high powereither electron majority carrier (N-channel FET, NPN BJT) or hole majority carrier (P-channel FET, PNP BJT)either linear (used in amplifier and oscillator circuits) or switching (used in digital logic circuits)etc.
Why fet is preferred over the bjt?
Disadvantage:Easy to damage when compared to BJT
What is difference between bjt and scr?
BJT is nothing but the addition of two PN junction diodes. There are two types of BJT= P-N-P or N-P-N P-N N-P + or + N-P = P-N-P P-N =N-P-N SCR is a thyristor which is made adding two BJTs. Of course they are made of sillicon. Exempli gratia: P-N-P + + N-P-N = P-N-P-N comparison between scr bjt and mosfet Check the related link for further information.
What is the difference between BJT and NPN transister?
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.
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
Are the Bipolar Junction Transistor and the Transistor the same thing?
Sort of. The Bipolar Junction Transistor, or BJT, is a type of transistor. But the term transistor applies to a much wider family of components than just the Standard BJT. A rough list of the other common types of transistors includes:Field effect transistors, or FETs, including both Junction types and Metal-oxide Semiconductor types: JFETs and MOSFETs. and also UJTs or unijunction transistors.In a basic electronics course, though, if you say just 'transistors' it is assumed you mean BJTs.
How do you make ujt with npn and pnp transistors?
You dont. A UJT is a much simple device than either of those BJT's Maybe you want to make a multivibrator out of BJT's?
What applications would prefer the bipolar junction transistors over the field effect transistor?
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.
Where can one get information regarding BJT?
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.
Which is faster small signal bjt or power bjt?
It depends on the exact part numbers, but power devices are typically slower. There are, of course, RF power transistors, so you have to compare apples with apples.
Applications of hybrid pi model of bjt?
ApplicationsThe BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequencyapplications, such as radio-frequency circuits for wireless systems. Bipolar transistors can be combined with MOSFETs in an integrated circuit by using a BiCMOSprocess of wafer fabrication to create circuits that take advantage of the application strengths of both types of transistor.
Is it possible idenfiying bjt and fet on the circuit?
Identifying BJTs and FETs on the circuitIt is in fact possible to identify transistors in circuits. However, this depends on one's familiarity with the different types of BJT and FET constructions. Since the transistor is a three-terminal device, it is easy to differentiate it from other circuit elements such as resistors, capacitors and inductorswhich are all two-terminal devices. The only exceptions to this may include regulators; which though are not transistors are provided with three terminals.
What is the difference between the UJT and BJT transistors?
UJT (UniJunction Transistor): It is a transistor with only one junction and three terminals: an emitter (E) and two bases (B1 and B2). BJT (Bipolar Junction Transistor): This type of transistor consists of two junctions and three terminals, namely Emitter "E", Base "B" and Collector"C". There are two types of BJT, i) PNP and ii) NPN.
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.
