摘      要：To fill the continuous needs for faster processing elements with less power consumption causes large pressure on the complementary metal oxide semiconductor(CMOS)technology *** scaling scenario is not an option nowadays and other technologies need to be *** quantum-dot cellular automata(QCA)technology is one of the important emerging nanotechnologies that have attracted much researchers’attention in recent *** technology has many interesting features,such as high speed,low power consumption,and small *** features make it an appropriate alternative to the CMOS *** paper suggests three novel structures of XNOR gates in the QCA *** presented structures do not follow the conventional approaches to the logic gates design but depend on the inherent capabilities of the new *** proposed structures are used as the main building blocks for a single-bit *** resulted circuits are simulated for the verification purpose and then compared with existing counterparts in the *** comparison results are encouraging to append the proposed structures to the library of QCA gates.
