| Abstract: | To get voltage-mode multiphase sinusoidal oscillator with high accuracy,high stability and easy to be integrated,a multiphase sinusoidal oscillator was presented on the basis of balanced operational amplifier and its phase-identical and phase-reversing integrator.The oscillator could produce N sinusoidal output(N being even or odd) with equal-amplitude and equal-phase distribution,low passive sensitivity,independent adjustment of magnitude and frequency of the oscillator,and grounded capacitors,so that the ... |
