Outline Abstract Charge recycling concept in NORA logic Proposed charge recycling technique Case studies Conclusion
Abstract In this work, a design technique to reduce the energy consumption in no race (NORA) circuits is presented. The no race (NORA) circuits, which is based on the charge recycling concept to reduce dynamic energy dissipation. Calculations proved that energy savings higher than 20% can be achieved.
1.8% delay increase. energy-delay product reduction is 5.9%. silicon area cost is 5.7%.
Conclusion It is based on the charge recycling approach and uses a unidirectional charge transfer topology and a new clocking scheme to allow charge recycling. The proposed clocking scheme, the elimination of the short circuit current is achieved. The proposed technique is characterized by insignificant delay penalty so that considerable reductions in the energy-delay product can be achieved.
