In this paper a single output self-checking n-input comparator is presented. The proposed circuit, which can be used as n-variable two-rail checker or as equality checker features a compact structure, is Totally-Self-Checking or Strongly Code-Disjoint with respect to a wide set of realistic faults, and requires a limited set of input code words for fault detection (thus it can be used to implement also embedded comparators).
