The fractional-order double-scroll chaotic system has been studied before as well using passive RC-ladder and tree-based structures but in this paper the requisite fractional-order integration has been accomplished through an integer-order multiple-feedback topology. As compared to double or multiple scroll chaotic systems existing in the open literature, the proposed realization offers the advantages of (a) low-voltage implementation, (b) integrablity as the design is resistor- and inductor-less and only grounded components have been employed in the design, and, (c) electronic tunability of the fractional order, time-constants and gain factors. In order to demonstrate the usefulness of the chaotic system, a simple secure message communication system has been designed and verified for its operation. The theoretical predictions of the proposed implementations have been verified by using 0.35[Formula: see text][Formula: see text]m complementary metal oxide semiconductor (CMOS) process file provided by Austrian Micro System (AMS). <\/jats:p>","DOI":"10.1142\/s0218126618500068","type":"journal-article","created":{"date-parts":[[2017,6,12]],"date-time":"2017-06-12T04:09:20Z","timestamp":1497240560000},"page":"1850006","source":"Crossref","is-referenced-by-count":21,"title":["Realization of Fractional-Order Double-Scroll Chaotic System Using Operational Transconductance Amplifier (OTA)"],"prefix":"10.1142","volume":"27","author":[{"given":"Mohammad Rafiq","family":"Dar","sequence":"first","affiliation":[{"name":"Department of Electronics and Instrumentation Technology, University of Kashmir, Hazratbal 190006, Srinagar, Jammu and Kashmir, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nasir Ali","family":"Kant","sequence":"additional","affiliation":[{"name":"Department of Electronics and Instrumentation Technology, University of Kashmir, Hazratbal 190006, Srinagar, Jammu and Kashmir, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2514-5703","authenticated-orcid":false,"given":"Farooq Ahmad","family":"Khanday","sequence":"additional","affiliation":[{"name":"Department of Electronics and Instrumentation Technology, University of Kashmir, Hazratbal 190006, Srinagar, Jammu and Kashmir, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2017,8,23]]},"reference":[{"key":"S0218126618500068BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/82.246163"},{"key":"S0218126618500068BIB002","first-page":"47","author":"Freeman J.
