The article focuses on the defects modeling of secured CMOS circuits, implemented in Quasi Delay Insensitive (QDI). We analyze the static and the dynamic behavior of resistive bridges as a function of its unpredictable resistance. SPICE simulations were performed for 45nm CMOS technology. Simulation results are given for the conditions of defect detection and for the delay induced by the resist...

Recent advances in computing and telecommunication technologies require ultra-highspeed and high-precision devices in the digital domain for their realization. The clock frequencies of semiconductor devices have increased beyond expectations, but will not be able to solve the above-mentioned problems in the near future. At this point, superconductor electronics (SCE) technology is a promising c...

Electromagnetic field diffusion in superconductors with gradual resistive transitions may exhibit a peculiar ~anomalous! mode which does not exist in superconductors with sharp ~ideal! resistive transitions. This is a ‘‘standing’’ mode. In the case of this mode, the electromagnetic field on a superconductor boundary increases with time, while the region occupied by the electromagnetic field wit...
