Bias temperature instability is a shift in threshold voltage with applied stress. When the shift exceeds some specified value, typically 30 mV, the device is considered to have failed. For pFETs, the threshold voltage corresponds to a negative gate bias, and so negative bias temperature instability (NBTI) is a more serious concern ...
