This paper discusses the design methodology of a voltage and temperature-sensitive ring oscillator (VT_RO), whose frequency has a similar dependence on voltages and temperatures as that of worn-out stress strength of a gate time-dependent dielectric

The authors propose an on-chip wear-out monitoring technique, which is based on monitoring the environmental conditions experienced by a digital circuit. The frequency of the T-sensitive ring oscillator (RO) emulates the wear-out stress strength caus

The on-chip stress monitor was experimentally implemented in a 28 nm automotive micro-controller-unit (MCU) to demonstrate the contribution to long-term fatigue monitoring of the MCU as well as short-term anomaly finding of the system. The monitor co

We propose an on-chip bias temperature instabilities (BTI) monitor by using standard cell based unbalanced ring-oscillator (RO). The monitor consists of NAND and NOR with extremely large difference in drive strength, which enables 4.2x sensitivity to

We propose wear-out estimator of remaining lifetime, which consists of two types of custom ring oscillators (ROs) and cumulative stress counters only. This on-chip estimator operates independently without disruption of MCU main operations and is aime

An area effective delay cell can be achieved in FinFET device with effective utilization of its parasitic capacitance, even though it is considered as disadvantage. We confirmed that parasitic capacitance of local interconnect can be a benefit for a
