Accelerated Evaluation Method of Temperature Switching Irradiation for ELDRS of Bipolar Voltage Comparator

With different irradiation methods, ionizing radiation responses of bipolar voltage comparators of three manufacturers were investigated. The results show that the input bias current and power current are the most sensitive parameters, and the input offset voltage is only sensitive to total dose in working state. Different bipolar voltage comparators from different companies have diverse radiation responses due to various crafts. This method can perfectly simulate and conservatively evaluate low dose rate damage of those devices in various bias conditions.
