Advanced nanometer circuits are susceptible to errors caused by process, voltage, and temperature (PVT) variations or due to a single event upset (SEU). State-of-the-art design-for-variability (DFV)-aware flip-flops (FFs) suffer from their area and timing overheads. By utilizing C-element modules, two types of FFs are proposed for error detection and error correction.
