In this work, a design technique to reduce the energy consumption in NO RAce (NORA) circuits is presented. The technique is based on a unidirectional switch topology combined with a new clocking scheme permitting both charge recycling between circuit nodes and elimination of the short circuit current. Calculations proved that energy savings higher than 20% can be achieved. Simulation results from NORA designs in a 0.18-mum CMOS technology are presented to demonstrate the effectiveness of the proposed technique to achieve both energy and energy-delay product reduction
