How to Connect a Transistor in a Circuit for Current Amplification Circuit Diagram BJT amplifier is basically a bipolar junction transistor operated in the active region. It increases the strength of the input signal and produces an amplified output. Depending upon the quantity amplified by the circuit, the BJT amplifier could be a voltage, current, or power amplifier. Types of BJT Amplifiers This tutorial actually meant to explain the practical importance of the well known transistor theories, characteristics plots and make use of them to design a high gain amplifier circuit using a single transistor and minimum number of other components. We will analyze certain transistor characteristics and theories, summaries them, and by the end of this tutorial we will be designing a high
Transistors can act as amplifiers while they are functioning in the active region or when it is correctly biased. We use a transistor as an amplifier when we want to amplify the input signal. The power gain of an amplifier is defined as the product of the current gain and voltage gain of the amplifier. It is also defined as the rate of Applications of Transistor as an Amplifier. These types of amplifiers enable the amplification of radio signals. Amplifiers are used in wireless communication. Its used to Increase the strength of the signal. Conclusion . We have different configuration of amplifiers but we are using common-emitter configuration in the case of the amplication.
How Transistor works as an Amplifier Circuit Diagram
-A separate power source must be connected to the collector of the transistor because a transistor is an active device, which means it needs power in order to operate. Check the power requirements of the transistor in use. So now you know how to connect a bipolar NPN transistor for amplification.
