Abstract

Abstract Quantum dot cellular automata (QCA) is a emerging nanotechnology that promises smaller size and lower power consumption, with faster speed compared to the transistor-based technology. In this paper, we have proposed novel 8-into-3 bit simple encoder, 4-into-2 bit priority encoder, scan flip-flop, and pseudo-random bit sequence generator designs in QCA. These circuits are useful components for the design of many logical and functional circuits. Simulation results of the proposed QCA circuits are obtained by using the QCA designer tool. The correctness of the proposed circuits is hence confirmed.
