Adders are essential components of computing circuits that play an important role in computing speed. This article proposed a new design for a single-bit current mode full adder using the field effect transistors based on carbon nanotubes to enhance the speed and reduce the occupied space on the chip. The correct combination of the majority function, the current mirror technique, and the sum value on carry reduced the delay of all adder circuits. The simulations have been done by HSPICE software and based on the provided standard model of 32 nm with CNTFET technology. The proposed design has improved by 55% in terms of delay. The PDP level in the proposed design has decreased by 63% compared to the previous designs.
