—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%… (More)
— We present in this paper a new security protocol especially suited for sensor networks. This protocol uses a novel encryption method for secure message transmission. We present the details of this encryption scheme along with experimental results performed on a network simulator.
We propose a new concurrent soft and timing error detection circuit that exploits the time redundancy approach to achieve tolerance with respect to transient and delay faults. The idea is based on current mode sense amplifier topologies to provide fast error detection times.
— High reliability requirements in many modern applications make soft errors an extremely important design aspect and pose new challenges in nanometer technologies. In addition, timing faults that may escape fabrication tests become a real concern in high complexity, high frequency designs. To confront this situation, a concurrent error detection and… (More)
