Who collector base current when emitter is off?
When the emitter of a bipolar junction transistor (BJT) is off, the collector-base junction is typically reverse-biased, meaning that the collector current is minimal or negligible. In this state, the collector-base junction does not conduct significant current because the emitter does not provide carriers to the base. As a result, the collector current is effectively zero, and the transistor is in its cutoff region.
What is PNP?
it is a bipolar junction transistor having p-type emitter & collector terminal and , n-type base terminal .
What bias conditions must be present for the normal operation of a transistor ampilifier?
Assuming you mean a bipolar junction transistor (BJT): 1. Reverse bias on the collector-base junction. 2. Forward bias on the base-emitter junction, that is 3. Sufficient to give the correct operating point of collector voltage/collector current.
What are PNP and NPN?
In most discrete bipolar junction transistors the substrate is the collector. In monolithic integrated circuits the bipolar junction transistors are electrically isolated from the substrate, either by reversed biased junctions or insulator (e.g. sapphire). Some older bipolar junction transistor types (usually made with germanium) the substrate is the base. In bipolar point contact transistors the substrate was the base.
Discuss how bipolar junction transistor used as a voltage amplifier?
A bipolar junction transistor (BJT) can be used as a voltage amplifier by operating it in the active region, where it can increase the voltage of an input signal. In this configuration, a small input voltage applied between the base and emitter controls a larger current flowing from the collector to the emitter. The output voltage is taken across a load resistor connected to the collector, and the amplified output can be significantly higher than the input. The gain, or amplification factor, depends on the transistor's characteristics and the configuration of the circuit, such as common-emitter or common-collector arrangements.
How do you reverse bias base collector junction?
To reverse bias a base-collector junction in a bipolar junction transistor (BJT), you need to apply a positive voltage to the collector relative to the base for an NPN transistor (or a negative voltage for a PNP transistor). This involves connecting the collector terminal to a higher potential and ensuring the base terminal is at a lower potential. As a result, the depletion region at the base-collector junction widens, preventing current flow between the collector and base. This condition is essential for transistor operation in certain configurations, such as in cutoff mode.
What BJT stand for?
Unless it is some leet speak term I am not aware of, BJTstands for Bipolar Junction Transistor or (less common) Business Japanese Proficiency Test.
Why high noise in bipolar junction transistor?
In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor
Why ordinary transistor is known as bipolar junction transistor?
Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction
What separates the three regions in a BJT?
Two junctions namely emitter-base junction and collector-base junction separates regions in a transistor.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
Why is collector current increased slowly with the increase of collector to emitter voltage of a common emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
