The realization of Fractance device is an important topic of research for the people working in Fractional Calculus, control systems, signal processing, and other allied fields. Having multifaceted applications, the realization of the device has gained importance from the past few years. The important step in the realization of Fractance device is finding the rational approximation that best fits its behavior. In this paper, the rational approximation is calculated using the continued fraction expansion formula. The rational approximation thus obtained is synthesized as a passive circuit using MATLAB. The active circuit is obtained by making use of the Operational Amplifier. The passive active circuits are simulated using TINA-TI software. The working of the proposed circuits is studied. It has been observed that both theoretical and simulated results match each other.
