What is CE CB CC configuration?
Common Base (CB) Configuration: no current gain but voltage gain. Common Collector (CC) Configuration: current gain but no voltage gain. Common Emitter (CE) Configuration: current gain and voltage gain.
What are the characteristics of CC?
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 CB configuration?
Definition: The configuration in which the base of the transistor is common between emitter and collector circuit is called a common base configuration.
What is common collector configuration?
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 are the characteristics of CC amplifier?
Common Collector Transistor Amplifier Characteristics
| Parameter | Characteristics |
|---|---|
| Power gain | Medium |
| Input or output phase relationship | Zero degree |
| Input resistance | High |
| Output resistance | Low |
What is CE configuration?
Definition: The configuration in which the emitter is connected between the collector and base is known as a common emitter configuration. The input circuit is connected between emitter and base, and the output circuit is taken from the collector and emitter.
What are the characteristics of CB amplifier?
Characteristics of Common Base Amplifier Circuit
- High voltage gain.
- Low current gain.
- Low power gain.
- Input and output phase relation is 0o.
- It has low input impedance.
- It has high output impedance.
What are the differences between CE CB and CC amplifiers?
As the input and output are in phase, there is no phase reversal. If CC configuration is considered for amplification, though CC amplifier has better input impedance and lower output impedance than CE amplifier, the voltage gain of CC is very less which limits its applications to impedance matching only.
What are the applications of CB configuration?
There are some applications of common base transistor amplifier which are given below,
- It is mainly used at high frequencies where low source resistance is common.
- It is used for impedance matching in circuits with very low output resistances to those with a high input resistance.
