Abstract

This paper presents a transient Pulse Dually Filterable and online Self-Recoverable (referred to as PDFSR) latch. Based on soft error masking property of C-element and using built-in delayed paths combined with a Schmitt inverter, a single event transient (SET) pulse could be dually filtered. Meanwhile, mutually feeding back mechanism of multiple C-elements was constructed to retain data, which makes the latch self-recoverable from a single event upset (SEU). Simulation results have demonstrated the SET filtering ability and SEU resilience at the cost of only 2.0% area-power-delay-width product increase on average, compared with the similar latches.
