Quantum dot cellular automata magnitude comparators
Bahniman Ghosh, Shoubhik Gupta, Smriti Kumari · 2012
In this paper, first a 1-bit magnitude comparator design is presented that reduces the number of QCA cells compared to previously reported design. The proposed design requires only about 49% of the area as compared to previous design with the same speed and clocking performance. Then, we have proposed novel 2 and 3 bit comparator designs in QCA.
