Preliminary study of NOR digital response to single pMOSFET dielectric degradation

The voltage-time domain (VT) characteristics of the CMOS NOR logic circuit are investigated using a switch matrix technique (SMT). VT performance is analyzed following gate oxide wearout in a pMOSFET, induced by applying a constant voltage stress (CVS) at -4.0 V. Results for the NOR VT characteristics show approximately 30% increase in rise time a considerable digression from nominal operation
