چکیده

Complementary metal-oxide semiconductor (CMOS) technology has been the industry standard to implement Very Large Scale Integrated (VLSI) devices for the last two decades. Due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. Quantum-dot cellular automata (QCA) is one of the alternative technologies proposed as a replacement solution to the fundamental limits of CMOS technology. QCA has the potential to be one of the features promising nanotechnologies because of its higher speed, smaller size and lower power consumption in comparison with transistor-based technology. This work proposes optimized QCA RS (Reset Set) flip flops. The proposed structures are simulated and validated using QCADesigner software. In comparison with the previous works the proposed QCA RS flip flops require the minimum number of cells, area and delay. Also, in comparison with CMOS technology our QCA designs are more efficient in terms of area, delay and frequency. Therefore, these structures can be used to design nanoscale circuits
