Is common collector called emitter follower?

In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer.

What is the difference between common collector and emitter follower?

The main difference between the two will be where the output is taken. For the common emitter amplifier, we will take the output at the collector of the transistor. For the emitter follower, the output will be taken at the emitter of the transistor.

How does an emitter follower work?

Emitter Follower. This is an emitter follower or buffer amplifier circuit, where the output is simply equal to the input minus a diode drop (about 700mV). It provides low output impedance to any circuit using the output of the follower, meaning that the output will not drop under load.

What is the function of emitter follower in a circuit?

The emitter follower is widely used as a buffer amplifier to reduce the loading on the previous stage and provide a lower impedance output for any following circuits.

What is the gain of emitter follower?

In practice, the voltage gain of an emitter follower is between 0.8 and 0.999.

What is a common emitter transistor amplifier?

The common emitter amplifier is a three basic single-stage bipolar junction transistor and is used as a voltage amplifier. The input of this amplifier is taken from the base terminal, the output is collected from the collector terminal and the emitter terminal is common for both the terminals.

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.

What is the advantage of emitter follower?

The emitter follower is widely used as a buffer amplifier to reduce the loading on the previous stage and provide a lower impedance output for any following circuits. The electronic circuit design for the stage is also very straightforward and easy to accomplish.

Which of the following is the main advantages of emitter follower?

The advantage of this circuit is that the transistor can provide current and power gain; the transistor draws little current from the input. It provides low output impedance to any circuit using the output of the follower, meaning that the output will not drop under load.
