With the continuous increase of integration densities
and complexities, secure integrated circuits (ICs) are more and
more required to guarantee reliability for safety-critical
applications in the presence of soft and hard faults. Thus, testing
has become a real challenge for enhancing the reliability of
safety-critical systems. This paper presents a Self-Test and SelfRepair
approach which can be used to tolerate the most likely
defects of bridging type that create a resistive path between VDD
supply voltage and the ground occurring in analog CMOS
circuits during the manufacturing process. The proposed testing
approach is designed using the 65 nm CMOS technology. We
then used an operational amplifier (OPA) to validate the
technique and correlate it with post layout simulation results.
