This The basic objective of the paper is to realize a fractional order active filter using fractional order devices (FOD) [1] and study its performance. Low pass, band pass and high pass filter response have been realized.  For this, a KHN type fractional biquad filter [2] has been considered. It requires two fractional order devices of order α and β (0 < α, β ≤ 1). The frequency response of the filter, obtained experimentally has been compared with simulated results using MATLAB/SIMULINK and also with PSpice (cadence PSD 14.2), where the fractional element is approximated with a Domino Ladder circuit [3].
