Decimal to Excess-3 and Excess-3 to Decimal Code Converters in QCA Nanotechnology

Nowadays Quantum-dot Cellular Automata (QCA) is one of the new technologies in nanoscale which can be used future circuits. Most digital circuits are implemented with CMOS technology, but has some problems like power consumption and circuit size. So, for solving these a method presented. It clear that converters play crucial role world. due to aforementioned point, this paper, two code converters, containing an excess-3 decimal, decimal converter The tile design proposed quantum-dot cellular automata nanotechnology. gives unique block majority NOT gates. This property facilitates integration. Both have 1.75 clock cycles delay energy dissipation about 100meV. In converter, 516 cells used, occupy area equal 0.43µm2 also converter. 321 0.28 µm2.
