Circuit Diagram Of Function Generator Using Op Amp

Function generators are an essential tool for a range of tasks, from testing and measuring circuits to providing a reference signal for calibrating test equipment. In this article, we’ll look at how to build a function generator using an operational amplifier (op-amp) and other components.

Function generators create signals ranging from low frequency sine waves to high-frequency square waves. They are essential for applications such as radar systems, communication systems, and automation. The frequency of the output waveform can be varied, allowing it to generate different types of signals.

For our function generator circuit, we’ll be using an op-amp and other components in order to create a stable output signal. The circuit diagram of the function generator is shown below.

Starting with the power supply, the 12V and ground terminals provide the necessary voltage for the circuit to operate. Next, the input voltage is applied to the non-inverting and inverting inputs of the op-amp. The output of the op-amp is then sent through the frequency response network, which consists of two resistors and two capacitors. This network helps to shape and modify the output signal so that it resembles a sine wave.

The frequency of the output signal can be adjusted by varying the values of the resistors and capacitors in the frequency response network. For example, increasing the value of one of the resistors will reduce the frequency of the output signal, while increasing the value of one of the capacitors will increase the frequency of the output signal.

Finally, the output of the frequency response network is sent to the output stage, where it is amplified and sent to the output terminal. This terminal can be connected to a speaker or an oscilloscope, allowing the output signal to be heard or monitored.

Building a function generator circuit using an op-amp and other components is a relatively simple task that can be accomplished within a short period of time with very little hardware or knowledge. By following the circuit diagram and adjusting the values of the resistors and capacitors in the frequency-response network, anyone can create a function generator that is capable of generating a range of signals.
