The effects of hot-electron degradation on analog MOSFET performance

Abstract
Many analog MOSFET performance parameters are found to be very sensitive to hot-electron stress, especially compared with digital parameters that are normally monitored. Drain output resistance degradation is characterized in detail using existing hot-electron reliability concepts and lifetime prediction models. The impact of drain output resistance degradation on the performance of a CMOS single-ended output differential amplifier is found to be a sensitive function of the particular circuit design and operating conditions.<>
