![]() For this circuit, we choose the 2N3904 transistor.įor a lot of the values of the components we actually compute, you won't be able to find those precise values. ![]() The transistor that is chosen can really be any BJT NPN transistor. ![]() ![]() This circuit works as a great voltage amplifier when a more precise and sophisticated op ap IC isn't available or a We will also show the maximum gain that a transistor can get based on the values we choose without clipping. We will show all the components that are necessary to build this circuit as well as how to choose the values of these components. Therefore, in this case, a voltage amplifier is built with all simple, discrete components. However, with a transistor and the correct biasing, we can produce the same voltage amplification effect of an op amp Voltage amplifiers, many times, are built with op amp circuits. Input 1V into the circuit, we can get 10V as output if we set the circuit for a gain of 10. In this project, we will show how to build a voltage amplifier with a transistor.Ī voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage. How to Build a Voltage Amplifier Circuit with a Transistor ![]()
