Abstract :
Using multi-valued logic can reduce chip interconnections, which can have a direct effect on chip area and interconnections power consumption. In recent years, due to the ability of Nano electronics in the design of multi-level circuits, research in this field has flourished. The sequential circuits, flip-flops are important components of processors and VLSI circuits. In this paper, for the first time, a ternary flip-flop with a pulse generator has been proposed, and also a ternary binary-decode flip-flop and the first flip-flop using a buffer have been introduced. Then these flip-flops are compared with themselves and previous circuits. Also, these flip-flops have been used in the design of the ternary counter. The simulation results with HSPICE software show the correct performance of the proposed circuits. There is a 20% improvement in delay and a reduction in the number of transistors in the STI pulse generator flip-flop model, 30% in the SP flip-flop, and 30% in the buffer flip-flop. Also, in the comparison table, the advantages and disadvantages of each have been examined.
