Synthesis of a fractional order audio boost filter
2017 29th International Conference on Microelectronics (ICM), 2017This paper introduces a fractional order audio band pass boost filter. The boost filter is part of the equalizer along with the cut filter: the first (e.g. the boost) is a band pass filter whereas the second is a stop band filter. These types of audio filters are widely used for their effectiveness in removing noise and echo.

Abstract A new category of fractional-order filters, realized without employing a fractional-order Laplacian operator is introduced in this work. This can be achieved through the utilization of an efficient curve fitting method which approximates the frequency-domain behavior of the filter and transposes the fractional-order transfer function into ...

Switched-current fractional-order filter designs
2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016Designs of switched-current fractional-order filters are presented in this paper. The derivation of the filters is performed through a transposition of the Functional Block Diagram of the continuous-time prototype filter into discrete-time domain using the bilinear s-to-z transformation.

CCII based KHN fractional order filter
2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013This work aims to generalize the analysis of the fractional order filter to work for the low-pass, band-pass and high-pass responses. So, general expression for the maximum and minimum frequency points and the half power frequency points will be derived.

Fractional-order integrator and its application in FLF fractional-order frequency filter
Proceedings II of the 28st Conference STUDENT EEICT 2022: Selected papers., 2022The main aim of this paper is to introduce the proposal of fractional integrator by approximation of the integer-order follow-the-leader-feedback topology (FLF). Current differencing transconductance amplifier (CDTA) is used in the integrator due to the higher versatility of this building block.
