High Frequency Sine Wave Generator Circuit

A pure sine wave has only a single or fundamental frequency ideally no harmonics are present.

High frequency sine wave generator circuit. This ic is generally used in inverter circuit and we have previously made a square wave generator using this ic by adding few resistors and capacitors in previous circuit we can obtain sine wave with ic 4047 as shown in the circuit diagram below. This circuit generate sine wave oscillation but actually we can modify the circuit to generate triangle or square wave function. Sine waves are waveforms which alternate in values during a cycle. Amplifier section this section is used to decrease output impedance or used to adjust dc offset or output amplitude of frequency.

How to build a sine wave generator with a 555 timer chip. This integrated circuit chip gives complete function to build a waveform generator function generator. This simple square wave generator circuit consists of a single ttl 74ls14 schmitt inverter logic gate with a capacitor connected between its input terminal and ground and the positive feedback required for the circuit to oscillate being provided by the feedback resistor. Frequency generator section to generate a stable frequency we have used icl8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine square triangular waveform.

High frequency waveform generator circuit diagram. Thus a sine wave may be the input to a device or circuit with the output harmonics measured to determine the amount of distortion. If you need a sine wave generator that can be set to any frequency in the 0 01 hz to 1 mhz or more take a look at the xr 2206. The xr 2206 is an older ic that is still available and a great way to generate sine square and triangle waves over a wide frequency range.

At high frequency levels the output waveform changes shape from a. We can also use ic 4047 to generate sine wave. In the above section we learned the basic version of ic sg3525 designed to produce a modified sine wave output when used in an inverter topology and this basic design cannot be enhanced to produce a pure sinewave waveform in its typical format. Sine wave oscillators are used as references or test waveforms by many circuits.

In this circuit we will show how we can build a sine wave generator with a 555 timer chip. Although the modified squarewave or sinewave output could be ok with its rms property and reasonably suitable for powering most. The circuit also can easily allow for amplitude adjustment. We then feed this triangle wave into a second integrator circuit which outputs a sine wave.

The 100kω potentiometer allows for a pretty good wide range of frequencies so that the circuit offers good frequency adjustment as a standard function generator would. Sine wave generator using 4047 ic.
