Stubby delay comparator in QCA: The C-Gate
B. Manohar Babu, P. V. S. R. Bharadwaja, K. Neelima · 2015
Quantum Dot Cellular Automata (QCA) is an appealing technology for designing very stubby power and high response digital Circuits. QCA is an computational model of Quantum theory. QCA Circuits are the corporal implementation of Cellular Automata by utilizing Quantum behavior. QCA is based on interplay rules amidst the cells placed on a tracery. A new gate called Comparison Gate shortened as C-Gate has been put forward in this work. The work is to explain the C-Gate and check its efficiency. The proposed gate can be extended for a lot many bits depending on the usage. The regular counter parts in QCA give very high delay as to C-Gate. This paper totally is opus of the C-Gate both theoretically and simulated version of it. The gate is simulated on Xilinx 14.2i and compared with other gates.
