Considering the importance of designing using alternative technologies for CMOS technology, in this paper, it has been tried to design important blocks of digital circuits in quantum dot cellular automata technology. In this regard, first, the optimal design was presented as a serial shift register with reset input. The number of cells used in this design is 111 and its occupied area is 0.1 μm. Then a new design was proposed as parallel in serial out shift register which used chip area of 0.3 μm and a total of 257 cells. The presented designs have suitable conditions in terms of the number of cells, occupied cross section area and delay. Further, to confirm the efficiency of these circuits, the structure of the new serial link was also presented. The proposed structures were verified by the QCADesigner and QCAPro software.
考虑到采用替代技术设计以替代CMOS技术的重要性,本文尝试在量子点细胞自动机技术中设计数字电路的重要模块。在这方面,首先,提出了一种具有复位输入的串行移位寄存器的优化设计。该设计中使用的单元数量为111个,其占用面积为0.1μm。然后提出了一种新的设计,即串入并出移位寄存器,其芯片面积为0.3μm,总共使用257个单元。所提出的设计在单元数量、占用横截面面积和延迟方面具有合适的条件。此外,为了确认这些电路的效率,还提出了新的串行链路结构。所提出的结构通过QCADesigner和QCAPro软件进行了验证。
