In this article, radiation effects and annealing characteristics of a bipolar analog-to-digital converter (ADC) are investigated in different biases and dose rates. The results show that ADC is sensitive to both the bias and dose rate. Under high-dose-rate irradiation, the ADC functions well, while under low-dose-rate irradiation, the parameters of ADC change obviously at low dose level, and the damage is significant at zero bias. Combining the fringing field with the space charge model, the underlying mechanism for this response is discussed.
