In electronics, a common collector amplifier is one of three basic singlestage bipolar junction transistor bjt amplifier topologies, typically used as a voltage. In the common emitter or grounded emitter configuration, the input signal is applied between the base, while the output is taken from between the collector and the. What is common collector connection or cc configuration. Different configurations of transistors common base, collector. The table which gives the main characteristics of a transistor in the three configurations is given above. The common collector amplifier has high input impedance and low output impedance. To fully describe the behavior of a transistor with cc configuration, we need two set of characteristics input characteristics and output characteristics. Commoncollector configuration of a transistor youtube.
A transistor has 3 terminals, the emitter, the base and the collector. In this article, we are going to learn about bipolar junction transistor configurations, common emitter, common base and common collector. Common collector configuration physics and radioelectronics. So far we have covered introduction of bipolar junction transistor we will learn in detail about different configurations of bipolar junction transistor in this post, as we know that bipolar junction transistor is a three terminal device, hence it can be. Common collector configuration of transistor detailed.
Linearity analysis of the common collector amplifier, or emitter. Transistor configuration common base, collector and emitter. Common collector amplifier basic electronics tutorials. Among all these three configurations common emitter configuration is mostly used type. Transistor configurations common emitter, base and. It is called the commoncollector configuration because ignoring the power supply battery. Using these 3 terminals the transistor can be connected in a circuit with one terminal common to both input and output in a 3 different possible configurations. Commoncollector configuration of a transistor topics covered. Common collector configuration concept video lecture from bipolar junction transistor of analog electronics for engineering ii year watch previous video of chapter. Common emitter connection, common base connection, and common collector. The power gain of the common collector amplifier is medium. Common collector configuration has current gain but no voltage gain.
Prototypes of small signal silicon transistors of types npn and pnp obtained. The common collector transistor configuration is also known as the emitter follower because the emitter voltage of this transistor follows the base terminal of the transistor. The collector is common to both the input and output circuit and hence the name common collector connection or common collector configuration. The three types of configurations are common base, common emitter and common collector configurations. Called the commoncollector configuration, its schematic diagram is shown in the figure below.
They are common emitter, common base and common collector configurations. Different configurations of transistors common base cb, common collector cc and common emitter ce input and output. Common collector amplifier has collector common to both input and output. The voltage gain of this transistor is unity, the current gain is high and the op.
Different configurations of transistors common base. 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. Input dc characteristics in commonbase configuration. Amplifier circuit can be designed by any of this type. Here we cover topics common collector configuration of the transistor circuits, characteristics, applications, disadvantage, why it is called emitterfollower circuit. Thus the collector terminal is common to both the input and output circuits. The bjt transistors have mainly three types of configurations. Basic electronics transistor configurations tutorialspoint. Our next transistor configuration to study is a bit simpler for gain calculations.
This type of configuration is called common collector, cc because the collector terminal is effectively. As we see in the previous article, there is basically three type of transistors connections. The common collector amplifier our next transistor configuration to study is a bit simpler for gain calculations. Called the common collector configuration, its schematic diagram is shown in figure below. 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.
