摘要
为了获得高精度、高稳定性、易集成的电压模式多相位正弦振荡器,以平衡运放及其同相和反相积分器为基础,给出多相位正弦振荡器.该电路能输出2组N(N为奇,亦可为偶)个等幅度、等相位分布的正弦输出,无源灵敏度低;振荡幅度与振荡频率可独立调节;所有电容接地,适宜集成.计算机仿真结果与理论分析一致.
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 system was easy to integrate. The result of computer simulation was consistent with that of theoretical analysis.
