In this paper several low power full adder topologies are

presented. The main idea of these circuits is based on the sense energy

recovery full adder (SERF) design and the GDI (Gate diffusion input)

technique. These subthreshold...

In this paper a new full adder (FA) circuit optimized for ultra low power operation is proposed. The

circuit is based on modified XOR gates operated in the subthreshold region to minimize the power consumption. Simulated results using 65nm...
