Area Efficient Decoder and Simulation Study Using Quantum Dot Cellular Automata

Authors: Aarthi Nadarajan

The progress and dominance of the microelectronics industry has been based on scaling and maintaining functionality at ever smaller scales. The resulting changes in size and package density have limitations due to the physical laws that govern the transistor paradigm. Quantum dot cellular automata (QCA) offer a solution to accomplish device functionalities at nanometer scales. This paper details QCA implementation with simulation results which intuitively prove they are much smaller than the same circuits in standard CMOS technology. The proposed area efficient decoder in this paper is optimal in terms of usage of number of quantum dot cells with a simpler clocking scheme and good performance. The field of quantum dots is relatively at its infancy with significant opportunities for future growth and real time implementations.
