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.
