A robust asynchronous full adder design corresponding to early output logic, synthesized using the elements of a standard cell library is presented in this paper. As the name suggests, the adder ensures gate orphan freedom and neatly fits into the self-timed system architecture. In comparison with many of the indicating full adder designs, which can be embedded in the self-timed system, it is found that the proposed full adder enables reduction in latency by 20.7%, occupies lesser area by 15.4% and features minimized average power dissipation by 8.6% against the best design metrics of its counterparts.
