In this study, a new sinusoidal fractional oscillator circuit in which the fractional low-pass filter and fractional differentiator form a closed loop has been introduced. The single series R−C pair and Valsa method have been used to imitate the fractional-order capacitor. Two different sinusoidal signals with different phases are available at output ports. An integer version of the proposed oscillator is not possible, only the fractional version is valid, that is a noticeable feature. The introduced circuit has been simulated by employing SPICE software. The proposed fractional oscillator is also verified by implementing circuit with AD817ANs and passive components, experimentally.

一种实用的分数阶正弦振荡器设计与实现

在这项研究中，介绍了一种新的正弦分数振荡器电路，其中分数低通滤波器和分数微分器形成闭环。单系列R-C对和 Valsa 方法已用于模拟分数阶电容器。输出端口提供两种不同相位的不同正弦信号。所提出的振荡器的整数版本是不可能的，只有小数版本是有效的，这是一个值得注意的特征。采用SPICE软件对所介绍的电路进行了仿真。所提出的分数振荡器也通过使用 AD817AN 和无源元件实现电路进行了实验验证。
