Which configuration is best suitable for amplification?

The most commonly used circuit configuration is the common emitter - this is used for many amplifier stages providing voltage gain.

Which configuration is better for amplification?

The Common Emitter configuration is the best and most widely used configuration for amplifier because of the following reasons: It is the only configuration that gives both voltage and current gain greater than unity.

Which configuration is mostly used in amplifier?

The CE configuration is the most widely used configuration and n-p-n transistors are the most commonly used transistors. Common emitter transistors are used most widely, because a common emitter transistor amplifier provides high current gain, high voltage gain and high power gain.

Why is CE configuration preferred for amplification?

Thus CE configuration is best for amplification because of its high power gain (due to its both high voltage and current gain) and hence most widely used.

Why CE configuration is preferred in amplifiers?

Common emitter circuit is preferred over a common base circuit in amplifiers because the resistance of the common emitter circuit is much less than that of the common base circuit. Also the power gain in the common emitter circuit is much higher than that in a common base circuit.

A SIMPLE Rule For Choosing An Amplifier | Ohms, Watts,

Which transistor is best for amplifier?

Why CE is better than CC and CB?

CE amplifier has a high input impedance and lower output impedance than CB amplifier. The voltage gain and power gain are also high in CE amplifier and hence this is mostly used in Audio amplifiers.

What is an amplifier configuration?

Three amplifier configurations are the common-emitter, the common-base, and the common-collector. The common-emitter (CE) configuration has the emitter as the common terminal, or ground, to an ac signal. CE amplifiers exhibit high voltage gain and high current gain.

Which BJT configuration is most suitable for voltage amplification Mcq?

Emitter follower: The Emitter-follower circuit is also known as a common collector configuration. It is called the emitter follower configuration because the emitter voltage follows the base voltage. It is mostly used as a voltage buffer.

Which amplifier configuration has highest input impedance?

But in most applications, common emitter and common collector amplifier circuits generally have high input impedances. Some types of amplifier designs, such as the common collector amplifier circuit automatically have high input impedance and low output impedance by the very nature of their design.

Why do we use common base configuration?

Even though the voltage gain is high, the current gain is very low and the overall power gain of the common base amplifier is low as compared to the other transistor amplifier configurations. The common base transistor amplifiers are primarily used in the applications where low input impedance is required.

What is CC amplifier?

The Common Collector Amplifier is another type of bipolar junction transistor, (BJT) configuration where the input signal is applied to the base terminal and the output signal taken from the emitter terminal. Thus the collector terminal is common to both the input and output circuits.

In which configuration a transistor will provide good power amplification?

The transistor provides good power amplification when they are used in common emitter configuration.

Which is better amplifier BJT or MOSFET?

The input impedance of MOSFET is very high like the megohms range whereas the BJT's input impedance ranges within the kiloohms. Therefore, MOSFET making is extremely perfect for amplifier based circuits. As compared with BJTs, MOSFETs have less noise. Here noise can be defined as the random intrusion within a signal.

Why FET is used instead of BJT?

Why is FET Preferred over BJT? Field-effect transistors provide high input impedance as compared with BJTs. The gain of FETs is lesser as compared with BJTs. The radiation effect of FET is less.

Why NPN transistor is mostly used?

The flowing of these electrons from emitter to collector forms the current flow in the transistor. Generally the NPN transistor is the most used type of bipolar transistors because the mobility of electrons is higher than the mobility of holes.

When an NPN transistor is used as an amplifier?

When NPN transistor is used as an amplifier, majority charge carrier electrons of N-type emitter move from emitter to base and then base to collector.

Is NPN and PNP transistor same?

There are numerous difference between NPN and PNP transistors, even though both are bipolar junction transistors. There are applications which makes transistors as a device- switch and amplifier. In a PNP transistor, the majority charge carriers are holes while in NPN the majority charge carriers are electrons.

Which BJT configuration is used as voltage amplification?

The most commonly used circuit configuration is the common emitter - this is used for many amplifier stages providing voltage gain. The emitter follower or common collector is also widely used.

In which configuration the current gain of the transistor amplifier is lowest?

Explanation: In Common base configuration, the input impedance is very low; While offering a high output impedance. Although the voltage is high, the current gain is low and the overall power gain is also low when compared to the other transistor configurations available.

What is CC configuration?

Definition: The configuration in which the collector is common between emitter and base is known as CC configuration. In CC configuration, the input circuit is connected between emitter and base and the output is taken from the collector and emitter.

Why CB configuration is not used for amplifier?

The common base amplifier configuration is not used as widely as transistor amplifier configurations. However it does find uses with amplifiers that require low input impedance levels. One application is for moving-coil microphones preamplifiers - these microphones have very low impedance levels.

Which configuration has the best frequency response?

An NPN transistor has a better frequency response than the PNP transistor because the mobility of electron is more and capacitive effect is less.

Does common base amplify current?

Common Base Amplifier Voltage Gain Characteristics

980 and . 995, it certainly does not increase the output current. It is only logical that if it does not increase current, then it should amplify voltage. Furthermore, the voltage gain (AV) of a common-base amplifier is the ratio of VOUT ÷ VIN.

Which of the following transistor configurations is best suitable for impedance matching in cascaded amplifiers?

The transistor connected in common collector configuration acts as a buffer for impedance matching.
