The transfer function of fractional-order differentiators and integrators can be approximated through the utilization of appropriate integer-order transfer functions. In order to achieve that, the Continued Fraction Expansion as well as the Oustaloup\u2019s approximations can be utilized. The accuracy, in terms of magnitude and phase response, of transfer functions of differentiators\/integrators derived through the employment of the aforementioned approximations, is very important factor for achieving high performance approximation of the fractional-order elements. A comparative study of the accuracy offered by the Continued Fraction Expansion and the Oustaloup\u2019s approximation is performed in this paper. As a next step, the corresponding implementations of the emulators of the fractional-order elements, derived using fundamental active cells such as operational amplifiers, operational transconductance amplifiers, current conveyors, and current feedback operational amplifiers realized in commercially available discrete-component IC form, are compared in terms of the most important performance characteristics. The most suitable of them are further compared using the OrCAD PSpice software.<\/jats:p>","DOI":"10.1142\/s0218126618501700","type":"journal-article","created":{"date-parts":[[2018,1,29]],"date-time":"2018-01-29T09:12:33Z","timestamp":1517217153000},"page":"1850170","source":"Crossref","is-referenced-by-count":69,"title":["Comparative Study of Discrete Component Realizations of Fractional-Order Capacitor and Inductor Active Emulators"],"prefix":"10.1142","volume":"27","author":[{"given":"Georgia","family":"Tsirimokou","sequence":"first","affiliation":[{"name":"Physics Department, University of Patras, Electronics Laboratory, University Campus, Rio Patras, GR 26504, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aslihan","family":"Kartci","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Communication, Brno University of Technology, Technicka 12, Brno 616 00, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaroslav","family":"Koton","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Communication, Brno University of Technology, Technicka 12, Brno 616 00, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norbert","family":"Herencsar","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Communication, Brno University of Technology, Technicka 12, Brno 616 00, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0817-7228","authenticated-orcid":false,"given":"Costas","family":"Psychalinos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2018,6,6]]},"reference":[{"key":"S0218126618501700BIB002","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126608004162"},{"key":"S0218126618501700BIB003","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cds.2010.0141"},{"key":"S0218126618501700BIB005","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-013-9580-9"},{"key":"S0218126618501700BIB006","doi-asserted-by":"publisher","DOI":"10.1002\/cta.2004"},{"key":"S0218126618501700BIB007","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2015.05.020"},{"key":"S0218126618501700BIB008","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126617501420"},{"key":"S0218126618501700BIB009","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126617501572"},{"key":"S0218126618501700BIB010","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2015.03.003"},{"key":"S0218126618501700BIB011","doi-asserted-by":"publisher","DOI":"10.1049\/PBCS032E_ch3"},{"key":"S0218126618501700BIB012","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-016-0243-5"},{"key":"S0218126618501700BIB014","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2017.03.021"},{"key":"S0218126618501700BIB015","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126618500238"},{"key":"S0218126618501700BIB016","doi-asserted-by":"publisher","DOI":"10.1109\/94.326654"},{"key":"S0218126618501700BIB017","first-page":"1","volume":"2013","author":"Caponetto R.","year":"2013","journal-title":"Adv.
