Abstract
- This paper presents two novel current-mode Full Adders based on Carbon Nanotube FET (CNFET). They comprise of three main parts: current-to-voltage converter, threshold detector and voltage-to-current converter. While other designs in the literature use either inverter or current source for detecting threshold, the new designs are based on a heuristic usage of an Ultra Low-Power Diode (ULPD) as voltage regulator. The use of diode does not lengthen the critical path and thereby ensuring high-speed operation. It does not increase power consumption significantly either. Simulation results by HSPICE and 32nm CNFET technology file demonstrate at least 19% higher performance in terms of energy consumption for the second proposed Full Adder compared to other traditional and state-of-the-art current-mode and mixed-mode designs.
