20.500.12556/DiRROS-30234 Design and efficiency enhancement of polar encoder based on universal logic gates utilizing QCA technology Oblikovanje in povečanje učinkovitosti polarnega dekodirnika na osnovi univerzalnih logičnih vrat z uporabo tehnologije QCA Nano-scale circuit designs can be implemented using a transistor-free method called Quantum-dot Cellular Automata (QCA). QCA circuits are denser, quicker, and need less energy than the commonly used transistor-based technologies. In QCA technology, like in many other technologies, it is crucial to send and receive information securely. The QCA-based polar encoder circuit is one of the circuits that makes this possible. There are some drawbacks to the polar encoders circuit in QCA technology, and a strong design with high speed and low cell count is also strongly required. This paper presents three new and largely used circuits for QCAbased polar encoders. The G2 (2-bit) design is a single-layer structure with 16 cells only and a total area of 0.02 μm2, while its delay is 0.5 clock cycles. A suggested G4 design would be 121 cells, requiring a total size of 0.16 μm2 with a delay of 1.50 clock cycles. The G8 design has a delay of 3.5 clock cycles at a total size of 0.8 μm2 with 564 cells. All designs are simulated using QCADesigner. The tests and the simulations prove the supremacy of the proposed circuits over the best previous circuits in terms of speed, number of cells, and space used for implementation. Zasnove vezij v nanometrskem merilu je mogoče izvesti z metodo brez tranzistorjev, imenovano kvantni celični avtomati (QCA). Vezja QCA so gostejša, hitrejša in potrebujejo manj energije kot običajno uporabljene tehnologije, ki temeljijo na tranzistorjih. Pri tehnologiji QCA je tako kot pri številnih drugih tehnologijah ključnega pomena varno pošiljanje in sprejemanje informacij. Polarno kodirno vezje, ki temelji na QCA, je eno od vezij, ki to omogoča. Vezje polarnih kodirnikov v QCA-tehnologiji ima nekaj pomanjkljivosti ter potrebuje močno zasnovo z visoko hitrostjo in majhnim številom celic. V tem članku so predstavljena tri nova in večinoma uporabljena vezja za polarne kodirnike, ki temeljijo na QCA. Zasnova G2 (2-bitna) je enoplastna struktura s 16 celicami in skupno površino 0,02 μm2, njena zakasnitev pa je 0,5 takta. Predlagana zasnova G4 bi imela 121 celic, za kar bi potrebovali skupno površino 0,16 μm2 , zakasnitev pa bi bila 1,50 takta. Zasnova G8 ima zakasnitev 3,5 takta pri skupni velikosti 0,8 μm2 in 564 celicami. Vse zasnove so simulirane s programom QCADesigner. Testi in simulacije dokazujejo premoč predlaganih vezij nad najboljšimi predhodnimi vezji glede hitrosti, števila celic in prostora, porabljenega za izvedbo. polar encoder quantum-dot cellular automata QCAdesigner nano communication nano electronic polarni kodirnik kvantne točke mobilni avtomat QCADesigner nano povezljivost nanoelektronski true false true Angleški jezik Slovenski jezik Neznano 2026-06-17 19:12:01 2026-06-18 06:01:13 2026-07-02 03:59:35 0000-00-00 00:00:00 2025 0 0 Besedilo v angl.; str. 87-94 no. 2 Vol. 55 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 621.38 0352-9045 10.33180/InfMIDEM2025.202 281473027 MIDEM_55(2025)2p2.pdf MIDEM_55(2025)2p2.pdf 1 F42D1F3915AD5CE22D263F4BA25C2E2F aa4e983001a3e2208a59601099b35f82164b017040ecfb1e379ae4cc8f557969 73d24deb-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46809 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/1950 1 a864f266-6a6f-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45804 \"https://www.midem-drustvo.si/journal_papers/MIDEM_55(2025)2p2.pdf 1 6a3e7ba1-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46786 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/1950 1 59abcd81-6aca-11f1-a3b9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45840 RAZ_Dongdong_Liu_2025.pdf RAZ_Dongdong_Liu_2025.pdf 1 491A3922963FDB2A985083F55E0B34B9 47f6097b96286dbcc60b0edc82b74bc4ef2ef216fc82308ce32dc7fa4178a15d 53e2beb3-7384-11f1-a785-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46398 Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale Informacije MIDEM 0 0 0
