In this study, the crosstalk effects are minimized in coupled multi-line wires based on repeater staggering in ternary logic. For more accuracy, the impact of the coupling capacitance is also considered in our calculations. Our results indicate that the number of repeaters required for optimizing the delay of the multilayer graphene nanoribbon (MLGNR) interconnect is, on average, 43% lower than multi-walled carbon nanotube (MWCNT) interconnect. Moreover, the optimized delay of the MLGNR interconnect is, on average, 48% lower than MWCNT interconnect. The ternary repeater insertion reduces the delay of the MWCNT and MLGNR interconnects carrying ternary signals by 61% and 51%, respectively. The staggered repeater insertion is applied as a practical approach for eliminating the crosstalk noise in the transmitted ternary signals in a multi-line coupled structure. Our results demonstrate that the delay and energy of the staggered repeater-inserted MLGNR interconnects are, on average, 42% and 37% lower than their MWCNT counterparts. Furthermore, the impacts of the process variations are investigated using comprehensive Monte Carlo simulations and the optimized ternary multi-line MLGNR interconnect functions correctly and considerably robustly compared to their MWCNT counterpart.
