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.

What is common collector transistor characteristics?

Common collector configuration have high input configuration and low output impedance. It has low voltage gain, high current gain and the power gain is medium. This configuration is mostly used for impedance matching, that is high impedance source is used to drive low impedance load.

What is the application of common collector configuration of transistor?

In the Common Collector transistor configuration, we use the collector terminal as common for both input and output signals. This configuration is also known as emitter follower configuration because the emitter voltage follows the base voltage. The emitter follower configuration is mostly used as a voltage buffer.

What are the applications of common collector configuration?

Applications

  • It is useful as an impedance matching device since its input impedance is much higher than its output impedance.
  • It is used in digital circuits with logic gates.
  • It is used as a switching circuit.
  • It is also used for cascade amplifier circuit isolation.

What are the types of configuration in a transistor?

The three types of configurations are Common Base, Common Emitter and Common Collector configurations. In every configuration, the emitter junction is forward biased and the collector junction is reverse biased.

What is the common base configuration?

In common base configuration, emitter is the input terminal, collector is the output terminal and base terminal is connected as a common terminal for both input and output. Thus the base terminal of a transistor is common for both input and output terminals and hence it is named as common base configuration.

What is common base configuration?

What is common collector used for?

The common collector or grounded collector configuration is generally used where a high impedance input source needs to be connected to a low impedance output load requiring a high current gain. Consider the common collector amplifier circuit below.

What are the advantages of common collector?

➢ The common-collector (CC) amplifier is usually referred to as an emitter-follower (EF). The input is applied to the base through a coupling capacitor, and the output is at the emitter. The voltage gain of a CC amplifier is approximately 1, and its main advantages are its high input resistance and current gain.

What is the use of common collector transistor?

The common collector or grounded collector configuration is generally used where a high impedance input source needs to be connected to a low impedance output load requiring a high current gain.

Which transistor configuration is most common?

Common emitter transistors
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.

What is common collector configuration of a transistor?

In this configuration, the base terminal of the transistor serves as the input, the emitter terminal is the output and the collector terminal is common for both input and output. Hence, it is named as common collector configuration. The input is applied between the base and collector while the output is taken from the emitter and collector.

How many terminals are there in a common collector amplifier?

A Common Collector Amplifier is formed from the basic Bipolar Junction transistor. Basically it is required to have four terminals so that two are preferred for the input and the remaining two is for output side. But it has only three terminals named as collector, base and the emitter.

What is emitter follower circuit in common collector circuit?

In common collector circuit, as we know input terminal is base and output terminal is an emitter. In this connection output value always follows the input supply voltage. Emitter value is always nearly equal to base input supply value. Hence here emitter follows base voltage so it called emitter follower circuit also.

What is the difference between common collector and grounded collector?

The input is applied between the base and collector while the output is taken from the emitter and collector. In common collector configuration, the collector terminal is grounded so the common collector configuration is also known as grounded collector configuration.
