Tradeoffs in Time-to-Digital Converter Architectures for Harsh Radiation Environments

Performance degradation of standard time-to-digital converters (TDCs) is inevitable due to the effects ionizing radiation. In this article, tradeoffs different mitigation techniques for TDC architectures are presented. As effect radiation challenging such high-performance circuits in state-of-the-art technologies, that can compensate have become a necessity TDCs operate these harsh environments. By looking into functionality focusing on improving tolerance, main weak and strong points architectures, including compensation circuitry, described. Possible solutions those
