Operational Amplifier-Based Fractional Device of Order s ±0.5

Part of the Advances in Intelligent Systems and Computing book series (AISC,volume 479)

Abstract

This paper brings an active fractional order device realization using an Op-amp (LM741) and few passive components. The fractional device model is derived from the rational approximation of fractional-order operator. Here continued fraction expansion is used to obtain the transfer function for the active realization of s ±0.5. RC-RC decomposition technique is used to synthesize the transfer function. The verification of the design is done using PSPICE to validate the theoretical as well as ideal result.

Keywords
