Impact of Neutron-Induced Displacement Damage on the ATREE Response in LM124 Operational Amplifier

摘要

The synergistic effect between displacement damage dose (DDD) and analog transient radiation effects on electronics (ATREE) in an operational amplifier (LM124) (opamp) from three different manufacturers is investigated. Pulsed X-ray experiments have highlighted ATREE sensitivity on devices significantly more important following exposure to fission neutrons than for unirradiated devices. A previously developed simulation tool is used to model ATREE responses taking into account the electrical parameters degradation due to displacement damage phenomenon. A good agreement is observed between model outputs and experimental ATREE results.
