First structure provides both inverting and non-inverting voltage-mode APF functions. This structure utilizes one differential difference dual-[Formula: see text] second generation current conveyor (DD-DXCCII) without [Formula: see text] terminals, one active resistor and one capacitor only. The use of active resistor makes the proposed structure electronically tunable. Therefore, the attributes such as use of single DD-DXCCII without [Formula: see text] terminals and electronic tunability make the proposed structure simple and attractive. Conversely, second proposed circuit structure of first-order APF enriches the quality of this paper as both inverting and non-inverting APF functions in both voltage and current forms are available simultaneously within the same circuit structure. This circuit is realized with the help of one DD-DXCCII, three active resistors and one capacitor. The second circuit structure also enjoys gain controllability feature along with electronically tunable pole frequency that proves to be very essential in many of the applications. Additionally, the proposed APF structures provide the demanding feature of cascadability along with chip fabrication support. Furthermore, the performance of proposed circuits is less affected by the non-idealities and parasitic of DD-DXCCII. PSPICE simulations are provided to validate the theoretical presumptions. <\/jats:p>","DOI":"10.1142\/s0218126621502686","type":"journal-article","created":{"date-parts":[[2021,4,19]],"date-time":"2021-04-19T15:47:42Z","timestamp":1618847262000},"source":"Crossref","is-referenced-by-count":8,"title":["New CMOS Realizable All-Pass Frequency Selective Structures"],"prefix":"10.1142","volume":"30","author":[{"given":"Jitendra","family":"Mohan","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, Jaypee Institute of Information Technology, Noida, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhartendu","family":"Chaturvedi","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Jaypee Institute of Information Technology, Noida, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9632-8435","authenticated-orcid":false,"given":"Atul","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2021,5,26]]},"reference":[{"key":"S0218126621502686BIB001","doi-asserted-by":"publisher","DOI":"10.1049\/el:19660107"},{"key":"S0218126621502686BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/PROC.1969.7488"},{"key":"S0218126621502686BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/PROC.1968.6731"},{"key":"S0218126621502686BIB004","volume-title":"Low-voltage Low Power CMOS Current Conveyors","author":"Ferri G.","year":"2003"},{"key":"S0218126621502686BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/TCT.1970.1083067"},{"key":"S0218126621502686BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/MWSCAS.2001.986176"},{"key":"S0218126621502686BIB007","doi-asserted-by":"publisher","DOI":"10.1078\/1434-8411-54100239"},{"key":"S0218126621502686BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2019.2915814"},{"key":"S0218126621502686BIB009","doi-asserted-by":"publisher","DOI":"10.3390\/electronics8070765"},{"key":"S0218126621502686BIB010","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126618500317"},{"key":"S0218126621502686BIB011","first-page":"162","volume":"14","author":"Kumar A.","year":"2018","journal-title":"Iran.
