Abstract :
This work proposes a novel built-in current sensor for detecting transient faults of short and long duration as well as multiple faults in combinational and sequential logic. Unlike prior similar strategies, which are formed by pairs of PMOS and NMOS sensors, the proposed scheme is a single sensor connected to PMOS and NMOS bulks of the monitored logic. In comparison with existing transient-fault mitigation techniques, the paper presents very competitive results that indicate no performance penalty, and overheads of only 26 % in power consumption and 23 % in area.
