How do I use a transistor as an amplifier in a circuit 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
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
Designing high gain amplifier using Transistor Circuit Diagram
The working of this high-power amplifier is similar to any simple amplifier circuit. what makes this circuit unique is the robust & high-power TIP122/127 Darlington transistor pair. An Audio input taken from a general audio transducer such as a mic acts as the DC control signal for the transistor Q1.
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.
