| Summary: | The synergistic effect of enhanced low dose rate sensitivity and single-event transients (SETs) in the bipolar dual operational amplifier LM158 is studied. The test results show a significant reduction in the SET amplitude and broadening in the SET waveform upon exposure to total ionizing dose radiation. These results are much more prominent for a low dose rate (LDR) irradiation of 0.01 rad(Si)/s than for a high dose rate irradiation of 10 rad(Si)/s. The greater gain degradation in the LM158 with LDR irradiation could be the direct cause of the reduction in the SET amplitude and broadening in the SET waveform, and this is corroborated through HSPICE simulations. |
