Radiation effects and annealing characteristics have been investigated for different types of bipolar operational amplifier with JFET differential pair input at five dose rates ranging from 1 to 6.4×10-5 Gy (Si)/s for the same total doses. The results show that the effects vary with the type of devices in the given dose rates
one of which only has the time dependent effects (TDE)
two of which not only have the TDE
but also the enhanced low dose rate sensitivity (ELDRS)
and the last one shows that there is no difference when the IC was irradiated at different dose rates
but there exists the effect of “post-radiation damage” as annealing at room temperture. Possible mechanisms for these effects are discussed.
