In this work, a novel implementation of a tunable fractional-order bandpass filter of order 2? is proposed. The transfer function of the presented filter is approximated using the second-order Continued Fraction Expansion (CFE) approximation technique. The filter transfer function is realized using the Inverse Follow the Leader Feedback (IFLF) structure. The Operational Transconductance Amplifiers (OTAs) are used to implement the filter circuit. Furthermore, the proposed filter is tunable by varying the value of only one bias current, which adjust the value of ?. The simulations are performed using Matlab and Cadence software with UMC 0.13? m CMOS technology. © 2019 IEEE.
