Advantages of transistors configuration
Advantages of different configurations of transistors are given below:
i. Common-Base Configuration:
Advantages of common-base configuration are given below:
* The common-base configuration has low input and output impedance which is used to drive loads of different impedances.
* This type of configuration offers low power consumption.
* The current gain(α) of this configuration is less affected by the change in temperature.
ii. Common-Emitter Configuration:
Advantages of common-emitter configuration are given below:
* Common-emitter configuration has high power gain which could be used when both current and voltage amplication is required.
* This type of configuration is easy to bias and therefore offers versality to various applications.
* Common-emitter configuration produces inverted output.
iii. Common-Collector Configuration:
Advantages of common-collector configuration are given below:
* This type of configuration has voltage gain close to unity which could be used for buffering of voltage.
* Common-collector configuration has high input impedance.
* There is no phase reversal between input signal and output signal.
BJT Configurations
A transistor is also called as bipolar junction transistor or simply BJT. It is called as bipolar as only two types of charge carriers, i.e. majority charge carriers and minority charge carriers are required to perform the operations on transistor. BJT is a current-controlled device as the output voltage, current or power is controlled by the input current in the transistor. As we know, BJT is a three-terminal device , so the three configurations- we will study in this article. The three main configurations are – common emitter , common base and common collector , which has its unique characteristics and applications respectively.
