Sine wave oscillators are used as references or test waveforms by many circuits. A pure sine wave has only a single or fundamental frequency—ideally no harmonics are present.

the key to designing an oscillator is to insure that Aβ = –1 (called the Barkhausen criterion), or using complex math the equivalent expression is Aβ = 1∠–180°.

Sine wave circuits pose a significant design challenge because they represent a constantly controlled linear oscillator. Sine wave circuitry is required in a number of diverse areas, …

Easily Tuned Sine Wave Oscillators One approach to generating sine waves is to filter a square wave. This leaves only the sine wave fundamental as the output. Since a square wave is …

This circuit uses a quad channel op amp with ±2.5-V supplies to generate a 10kHz, low-distortion sine wave. The amplifiers buffer each RC filter stage, which yields a low-distortion output.

This circuit generates a sine wave by first generating a square wave, at the required frequency, with amplifier A1 that is configured as an astable oscillator with the frequency determined by …
