This paper traces the history of the evolution of inverse analog filters (IAF) and presents a
review of the progress made in this area to date. The paper, thus, presents the current state …

Fractional-Order circuits and networks being a widely researched field lags in its
development due to the non-availability of its basic building block ie Fractional-Order …

The behavior of a fractional-order capacitors can be approximated using appropriately
configured RC networks, which implement an integer-order impedance/admittance function …

Fractional-order (FO) systems offer a unique flexibility of arbitrary slope matching in system
gain which is not possible in conventional circuit theory. This has made application of …

Abstract The design of (1+ α) order, 0< α< 1, low pass Butterworth filter approximated in
terms of an integer order continuous-time transfer function using a nature-inspired …

In this paper, a new two-steps design strategy is introduced for the optimal rational
approximation of the fractional-order Butterworth filter. At first, the weighting factors of the …

Fractional-order Butterworth filters of order 1+ α (0< α< 1) can be implemented by a unified
structure, using the method presented in this paper. The main offered benefit is that the cutoff …

Higher-order fractional filters with fully controllable frequency characteristics are realized in
this work, after fitting the filter's magnitude response data using a minimum-phase state …

Having an approximate realization of the fractance device is an essential part of fractional-
order filter design and implementation. This encouraged researchers to introduce many …

Abstract Two (α+ β)-order transfer functions realizing fractional-order band-pass filter
responses are presented and analysed, where 0< α≤ 1 and 0< β≤ 1. Generalizing the …
