Figure 10 Quadrature Sine Wave Oscillator
Figure 10 shows the circuit diagram for a quadrature sine wave oscillator. This circuit consists of two
integrators and a limiter circuit, and provides not only a sine wave output, but also a cosine output, that is,
it also supplies the waveform delayed by 90°. The output amplitude is essentially determined by the limiter
circuit.
