МАЖОРИТАРНІ НАНОСХЕМИ РЕГІСТРІВ

The article presents the results of the implementation of the latest technologies for automated modeling of trigger nanocircuits with majority logic for the design of ultra-fast nanoregisters. The created sequential devices use the technology of quantum cellular automata. Unlike microelectronic triggers, the nanotriggers proposed in the work are based on universal majority elements as elementary automata, combining the execution of logical functions with delay functions. This combination allows reducing the number of quantum cells to 25 versus (34 – 43) cells in existing analogues. Unique fourvariant implementations of trigger nanocircuits with separate inputs are proposed, which have become possible to program with forbidden combinations of logical units for input signals and which are unacceptable for microelectronic components with memory. This leads to a significant acceleration of computer design of a full set of sequential nanocircuits. A feature of multi-input nano-registers of parallel action with recording and memoriz- ing the code of binary numbers and nano-registers with a shift towards the senior or junior digits. The article is devoted to the implementation of the majority logic of the functioning of modified nano-triggers with separate inputs, which makes it possible to implement forbidden combinations of input signals of logical units. This allows significantly accelerating the computer design of a full set of sequential nanocircuits. The modern automated design system QCA Designer synthesizes nano-register schemes and adequately models the timing diagrams of their performance.
