Which of the following terminals of BJT is extremely thin?

Base (B): The based region is thin and lightly doped. It provides proper interaction between emitter and collector.

Which of the following region in a BJT is the thinnest?

The base region of a BJT transistor is very thin and is lightly doped with current carriers. It is the region of a transistor which has opposite polarity charge carriers from the emitter and the collector regions.

Which terminal is very thin?

The base of a transistor is kept very thin compared to the collector and emitter so that most of the carriers(carriers means electron in case of NPN transistor and holes in case of PNP transistor) pass to the collector, injected from the emitter i.e, less number of electron-hole recombination take place and the whole ...

Which of these is the Thinest region of a transistor?

The base region is the thinnest region of the transistor and the electron concentration of this region, as a result, is the lowest among the three regions.

Which transistor is very thin and lightly doped?

Bases are lightly doped and very thin, it passes most of the emitter-injected electrons on to the collector.

Electrical Engineering: Ch 3: Circuit Analysis (34 of 37) Solving Basic Transistor Circuit (MESH) 1

Why base in a BJT is very thin?

Solution : The base region in a transistor is made very thin so that there is a better conduction of majority carriers from emitter to collector through base.

Why base in a BJT is very thin justify your answer?

The base in a BJT is a very thin barrier which should ideally let the electrons tunnel through without recombination mechanism occurring at the base junction at or above cut in voltage and through the operating voltage spectrum.

Why in a transistor A The base is thin lightly doped and B the collector is large in size?

Answer: The Base region is thin so that the majority charge carriers coming from emitter find themselves near the Base collector junction and move to collector instead of going to Baseterminal. It is lightly doped so that the depletion region is thin, electric field is strong and the resistance is small.

Which region in the BJT is highly doped?

Emitter provides majority charge carrier by which current flows in the transistors. Therefore, the emitter semiconductor is heavily doped and the base region is light doped and thin.

Which of the following in the BJT is the heavily doped region?

3. In a BJT, which of the following layers is heavily doped? Explanation: The emitter is the most heavily doped and contains the maximum amount of charge carriers.

Which region of BJT has maximum width?

The collector is the largest region of a BJT transistor.

What is Icbo and ICEO?

ICBO is the collector current with collector junction reverse biased and base open-circuited. ICEO is the collector current with collector junction reverse biased and emitter open-circuited.

How many terminals does a transistor have why base is kept very thin?

It has three terminals namely emitter, base and collector. The base is the middle section which is made up of thin layers.

Which of the following regions of transistors are respectively heavily doped and lightly doped?

Solution : In a bipolar junction transistor, emitter is heavily doped, base is lightly doped and collector is moderately doped.

Which region of the transistor is highly doped Mcq?

The emitter is heavily doped, so that it can inject a large number of charge carriers (electrons or holes) into the base.

Which of the following part of a bipolar junction transistor is lightly doped with impurities to enhance majority carriers?

The emitter is heavily doped, while the collector is lightly doped, allowing a large reverse bias voltage to be applied before the collector–base junction breaks down.

Which is heavily doped in transistor?

Emitter (E): It provides majority charge carriers by which current flows in the transistor. Therefore the emitter semiconductor is heavily doped.

Why Emmiter is heavily doped?

The reason the emitter is the most heavily doped region is because it serves to inject a large amount of charge carriers into the base, which then travels into the collector, so that switching or amplification can occur. In npn transistors, the n-type emitter injects free electrons into the base.

Why is the emitter heavily doped and the collector lightly doped?

The emitter is heavily doped, as more number of electrons pass through it, base is lightly doped as it only carries least current and the collector is moderately doped.

Which of the following is are the terminals of a transistor?

A transistor is an electronic device that contains three terminals named emitter, base, and collector.

What are the three terminals of a transistor?

Bipolar Junction Transistor (BJT)

The three terminals of BJT are base, emitter and collector. A very small current flowing between base and emitter can control a larger flow of current between the collector and emitter terminal.

Why is ICEO bigger than Icbo?

The ICBO flows from collector to base. You talk of ICEO when the base terminal is open. The ICBO will actually have to flow through the emitter to reach back the collector. The textbooks say, now the ICBO also gets amplified "just like IB", to get a bigger value : ICEO.

What is ICO and Icbo in transistor?

Icbo is the collector current with the base negative. This relates to the cut-off leakage when operating the transistor as a switch. Ico is generally the current at maximum Hfe/beta. The gain of any bipolar is not constant but has a maximum peak. Usually you want to bias/operate the transistor at/around this current.

What is the Icbo?

ICBO, the International Conference of Building Officials, was founded in 1922 and is headquartered in Lansing, Michigan. Founded as the Pacific Coast Building Officials Conference, ICBO has published the Uniform Building Code (between 1927 and 1997) and other related documents.

How many terminals does a BJT have?

The BJT (bipolar junction transistor) is a current-controlled electronic device main employed for amplification and switching purpose. It comes with three terminals called emitter, base, and collector.
