Abstract

A fractional order oscillator employing operational transconductance amplifiers (OTAs) and fractional capacitors has been presented in this paper. The Oustaloup approximation method is used to design the fractional order capacitors. Generalized fractional order theorems have been used to obtain the frequency of oscillation (FO) and condition of oscillation (CO). The stability of the proposed fractional order oscillator has been tested using pole-zero plots in the W-plane. PSPICE simulation and hardware result for the proposed oscillator have also been presented.

利用ota的分数阶振荡器
本文提出了一种采用运算跨导放大器(OTAs)和分数阶电容的分数阶振荡器。采用Oustaloup近似法设计分数阶电容。利用广义分数阶定理得到了振动的频率(FO)和振动的条件(CO)。用w平面上的极-零图测试了所提出的分数阶振荡器的稳定性。最后给出了该振荡器的PSPICE仿真和硬件结果。
