This paper presents a study of fractional order quadrature oscillators based on current-\ncontrolled current follower transconductance amplifiers (CCCFTA). The design\nrealisation and performance of the fractional order quadrature oscillators have been\npresented. The quadrature oscillators are constructed using three fractional capacitors\nof orders �± = 0.5. The fractional capacitor is not available on the market or in the\nPSPICE program. Fortunately, the fractional capacitor can be realised by using the\napproximate method for the RC ladder network approximation. The oscillation frequency\nand oscillation condition can be electronically/orthogonally controlled via\ninput bias currents. Due to high-output impedances, the proposed circuit enables\neasy cascading in current-mode (CM). The PSPICE simulation results are depicted,\nand the given results agree well with the anticipated theoretical outcomes.
