A common base NPN amplifier is used for high frequency applications as the base minimize oscillations at high frequency, separates the input and output. In a common base NPN amplifier the voltage gain is high, relatively low input impedance and high output impedance compared to the common collector.
What else can I help you with?
What is average amplifier?
The average amplifier is 60 to 200 amps.
What is horizontal and vertical amplifier in cathode ray oscilloscope?
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
When was the 1st amplifier made?
the first amplifier was made in the year 1909. this was the audio amplifier of vacuum tube type.
What is a microphone connected to?
A microphone is usually connected to an amplifier.
Is a microphone output or input?
input. The microphone gives a signal to the computer/radio/whatever you're using. it is input because when you speak into it,it gets in the amplifier and the amplifier processes it to came out as sound through the speaker
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.
Inputoutput and transfer characteristics of pnp and npn transistor in common base configuration?
result of output characteristics of npn transister in CB mode
Why is npn transistor called emmitor follower?
In an NPN transistor an emiter follower refers to an amplifier topology. The emiter follower configuration is when the emitter of a N-Type Bipolar Junction Transistor (BJT) is connected to the common point on a circuit (typically ground). This is not always the case, however, because many amplifier configuration exist.
Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.
What type of signal at the NPN output?
A: It always a voltage since it is a voltage amplifier
What is the output signal of a common base amplifier?
3Db
Main use of a Common base transistor amplifier is?
as voltage amplifiercurrent followeri am yoges
Which amplifier uses the base as the reference terminal for the input and output signal?
The amplifier that uses the base as the reference terminal for the input and output signal is the common-base amplifier. In this configuration, the input signal is applied to the emitter, while the output is taken from the collector. The common-base amplifier is known for its high frequency response and low input impedance, making it suitable for specific applications such as radio frequency amplification.
What is cb configuration of the transistor?
A sexy transistor are two type. NPN and PNP..... c means common b means base .
What are the majority carriers in the base region of an npn transistor?
holes are majority in base
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
How do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
