Abstract (2. Language): 
For immense demand of speedy high-end gadgets, chips are becoming denser, but Moore's law is falling flat lately. Complementary Metal-Oxide-Semiconductor (CMOS) technology is on its brink. Quantum-dot cellular automata (QCA) has become a potential alternative technology to provide faster speed with low power dissipation at nano-scale extent. Here, we proposed an efficient QCA design of 1-bit comparator. The proposed comparator required 59% less area and dissipated 82% less energy. QCA Designer has been used to design and simulate the proposed comparator. Finally, QCAPro tool has been employed for estimating energy dissipation.

Abstract (Original Language): 
Hızlı üst düzey cihazların büyük talepleri için çipler yoğunlaşmakta ancak Moore yasası son zamanlarda düşmektedir. Tamamlayıcı Metal-Oksit-Yarı iletken (CMOS) teknolojisi eşiğe ulaşmıştır. Kuantum noktalı hücresel otomasyon (QCA), nano ölçekte düşük güç dağılımıyla daha hızlı bir hız sağlamak için potansiyel bir alternatif teknoloji haline gelmiştir. Bu çalışmada, 1 bitlik karşılaştırıcının verimli bir QCA tasarımı önerdik. Önerilen karşılaştırıcı,% 59 daha az alan gerektirir ve % 82 daha az enerji tüketir. QCA Tasarımcısı, önerilen karşılaştırıcıyı tasarlamak ve simule etmek için kullanılmıştır. Son olarak, enerji yayılımını tahmin etmek için QCAPro aracı kullanılmıştır.
