【摘要】：在納米技術(shù)領(lǐng)域,量子元胞自動機(jī)(quantum dot-cellular automata,QCA)可作為傳統(tǒng)互補(bǔ)金屬氧化物半導(dǎo)體(complementary metal oxide semiconductor,CMOS)電路的替代方案,具有可觀的發(fā)展前景。QCA設(shè)備密度高,運(yùn)行速度快,且功耗極低。在QCA中,可逆邏輯有著廣泛應(yīng)用。研究者已開發(fā)多個基于QCA的可逆邏輯電路,但基于QCA的可逆二進(jìn)制減法器研究卻不多見。QCA低功耗和高電流密度的特點(diǎn),使其可用于設(shè)計納米尺度節(jié)能邏輯電路。然而,其對大量邏輯門的需求和不利的無用輸出,可能限制基于QCA邏輯電路的功能。我們利用QCA設(shè)計并實現(xiàn)了一個DG門,實現(xiàn)了DG門的普遍特征。利用該DG門的QCA部分,可以獲得新的可逆二進(jìn)制減法器。相比現(xiàn)有可逆減法器,我們設(shè)計的減法器量子成本低,無用輸出少。電路設(shè)計與模擬基于QCA Designer-2.0.3軟件。
[Abstract]:In the field of nanotechnology, quantum cellular automata (quantum dot-cellular automata,QCA) can be used as a substitute for traditional complementary metal oxide semiconductor (complementary metal oxide semiconductor,CMOS) circuits. Reversible logic is widely used in QCA. Researchers have developed a number of reversible logic circuits based on QCA, but the reversible binary subtraction based on QCA is not widely used in the design of nanoscale energy-saving logic circuits because of its low power consumption and high current density. However, its demand for a large number of logic gates and unfavorable output may limit the functionality of QCA-based logic circuits. We design and implement a DG gate with QCA, and realize the universal characteristic of DG gate. Using the QCA part of the DG gate, a new reversible binary subtraction can be obtained. Compared with the existing reversible subtraction, the quantum cost and useless output of the subtractive are lower. Circuit design and simulation are based on QCA Designer-2.0.3 software.
