In this work, we present a new dual-differential full-adder bit-slice design that can be used for implementing circuits with Concurrent Error Detection (CED) capability. The proposed design is suitable to realize applications needing diagnostics and maintenance in the field. The proposed design used a mixed DPL/PTL logic style design, requires only 24 transistors, and provides dual-differential outputs. To prove the proposed design efficiency, the circuit is designed and simulated using the standard 32 nm technology node. The proposed scheme can be used to ameliorate the circuit fault detection, fault-masking, and then fault tolerance capability. By using the proposed full-adder bit-slice, we have implemented and simulated a 4-bit ripple carry adder design realized using a mixed CMOS/DPL/PTL logic style design. The simulation results prove the acceptable electrical behavior of the implemented 4-bit ripple carries adder design.
