Design of four valued synchronous reversible counter based on the theory of three essential circuit elements A

Through the research on the theory of three essential circuit elements（ signal, net and load） and five-valued algebra, this paper presented a novel element level design scheme of four-valued D flip-flop. Then based on the characteristic of reversible counter, four-valued D flip-flop was used as the core component to design four-valued synchronous reversible counter which has reset function. Finally, The PSPICE simulation results indicated that the novel scheme has correct logic function.
