CNFET-based ternary inverter and its variability analysis

Multivalued Logic has attracted substantial interest of digital designers due to its potential of enhancing data content per unit area. This paper extensively analyses transient characteristics of CNFET-based ternary inverter and compares the variability of its different design metrics with those of CNFET-based binary inverter and shows that the variability of parameters of ternary inverter are much narrower than those of binary inverter. The proposed CNFET-based ternary inverter proves its robustness by exhibiting narrower spread in delay, average power, power-delay product (PDP) and energy-delay product (EDP) variability by 81.86%, 15.91%, 77.66% and 75% respectively. All the simulations have been performed on SPICE using predictive technology model (PTM) @ 16-nm technology node.
