چکیده    We are examining different configurations and circuit topologies for arithmetic components such as adder and compressor circuits using both symmetric and asymmetric work-function finfets. based on extensive characterization data,for the carry generation of a mirror full adder using symmetric devices,both leakage current and delay are decreased by 25% and 50%,respectively,compared to results in the literature. for the 14-transistor (14t) full adder topology,both leakage and delay are decreased by 23% and 29%,respectively,compared to the mirror topology. the 14t adder topology,using asymmetric devices without any additional power supply,achives reduction in leakage current by 85% with a small degradation of 7% in delay. the compressor circuits,using asymmetric devices for one of the proposed configurations,achieve reduction in both leakage current and delay by 86% and 4%,respectively. all simulations are based on a 25 nm finfet technology using the university of florida ufdg model. © 2013 farid moshgelani et al.
