The proposed filter operates in the current-mode and it is designed using Multi-Output Current Followers (MO-CFs), Dual-Output Current Follower (DO-CF), Dual-Output Adjustable Current Amplifier (DO-ACA) and Adjustable Current Amplifiers (ACAs) as\u00a0active elements within the presented topology of the filter. The filter possesses ability to\u00a0electronically control its order and also the pole frequency by changing the current gain of current amplifiers (ACAs) already present in the structure. Three different values of the order and pole frequency of the proposed low-pass filter were tested as an example. Design of the proposed filter is supported by simulation and experimental results. Simulations of the circuit are carried out in PSPICE simulator with behavioral models of used active elements. The experimental laboratory measurements are performed with the help of available devices forming equivalent circuits. Simulations and experimental results of the electronical control of the order and pole frequency are compared in this contribution. <\/jats:p>","DOI":"10.1142\/s0218126618500329","type":"journal-article","created":{"date-parts":[[2017,7,6]],"date-time":"2017-07-06T23:08:08Z","timestamp":1499382488000},"page":"1850032","source":"Crossref","is-referenced-by-count":29,"title":["Synthesis and Analysis of Electronically Adjustable Fractional-Order Low-Pass Filter"],"prefix":"10.1142","volume":"27","author":[{"given":"Jan","family":"Dvorak","sequence":"first","affiliation":[{"name":"Department of Telecommunications, Brno University of Technology, Technicka 12, Brno 61600, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukas","family":"Langhammer","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Brno University of Technology, Technicka 12, Brno 61600, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Jerabek","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Brno University of Technology, Technicka 12, Brno 61600, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaroslav","family":"Koton","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Brno University of Technology, Technicka 12, Brno 61600, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roman","family":"Sotner","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Brno University of Technology, Technicka 12, Brno 61600, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josef","family":"Polak","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Brno University of Technology, Technicka 12, Brno 61600, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2017,9,11]]},"reference":[{"key":"S0218126618500329BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2010.06.018"},{"key":"S0218126618500329BIB002","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cds.2010.0141"},{"key":"S0218126618500329BIB003","doi-asserted-by":"publisher","DOI":"10.1002\/cta.1995"},{"key":"S0218126618500329BIB004","doi-asserted-by":"publisher","DOI":"10.1002\/cta.2066"},{"key":"S0218126618500329BIB005","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-015-0226-y"},{"key":"S0218126618500329BIB007","doi-asserted-by":"publisher","DOI":"10.1587\/nolta.3.357"},{"key":"S0218126618500329BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/JETCAS.2013.2265797"},{"key":"S0218126618500329BIB009","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-014-9925-z"},{"key":"S0218126618500329BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/TED.2011.2166763"},{"key":"S0218126618500329BIB011","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/832468"},{"key":"S0218126618500329BIB012","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cds.2010.0366"},{"key":"S0218126618500329BIB013","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cds.2011.0239"},{"key":"S0218126618500329BIB014","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-012-9432-z"},{"key":"S0218126618500329BIB016","doi-asserted-by":"publisher","DOI":"10.1016\/j.mejo.2016.02.002"},{"key":"S0218126618500329BIB018","doi-asserted-by":"publisher","DOI":"10.1109\/JETCAS.2013.2266753"},{"key":"S0218126618500329BIB025","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-015-0222-2"},{"key":"S0218126618500329BIB026","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-016-0258-y"},{"key":"S0218126618500329BIB028","doi-asserted-by":"publisher","DOI":"10.1002\/cta.453"},{"key":"S0218126618500329BIB030","doi-asserted-by":"crossref","first-page":"2051","DOI":"10.1109\/TCSI.2008.918196","volume":"55","author":"Oustaloup A.","year":"2008","journal-title":"IEEE Trans.
