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.
