This article describes the Quadrature Sinewave Oscillator (TLV2472). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components: TLV2472.

Quadrature oscillator is another type of phase shift oscillator. This circuit produce two sine wave signal. One of them is shifted 90 degree from the other signal. The output that shifted 90 degree is called cosine signal and the other is called sine circuit has two output. Here is the circuit :
quadrature sinewave oscillator circuit schematic diagram
This circuit has three phase shifter sections. Each section is set to generate 90 degree phase shift. The frequency f would be equal to 1/2[pi]RC because R3C3=R2C2=R1C1. The value of the components might variate within their tolerance because when this circuit is tested, it generate 1.65 kHz rather than calculated 1.59 kHz.
