What is common collector circuit?

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.

What is another name for a common collector circuit?

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 voltage common collector?

The common collector amplifier is also called the emitter follower amplifier because the output voltage signal at the emitter is approximately equal to the voltage signal input on the base. The output impedance of the CC amplifier can be substantially less than the output impedance of the driving signal source.

Why it is called common collector?

Common-collector transistor amplifiers are so-called because the input and output voltage points share the collector lead of the transistor in common with each other, not considering any power supplies. The common-collector amplifier is also known as an emitter-follower.

What is voltage buffer?

A voltage buffer, also known as a voltage follower, or a unity gain amplifier, is an amplifier with a gain of 1. A voltage gain of 1 means that if the input voltage goes up by ΔV , then the output voltage is also designed to go up by the same ΔV .

What is the most important fact about the collector current?

What is the most important fact about the collector current? It is measured in milliampere. It equals the base current divided by the current gain.

What is common collector configuration?

Definition: The configuration in which the collector is common between emitter and base is known as CC configuration. The collector is common to both the input and output circuit and hence the name common collector connection or common collector configuration. …
