摘要

A radiation-hardened-by-design time-to-digital converter is presented, featuring a single-shot precision of 8 ps and a zero-dead-zone measurement range of 0 ps up to 3 s. The analog and digital building blocks, along with the overall chip architecture, are developed with a focus on radiation tolerance, enabling robust operation in time-of-flight and time-tagging applications in space.
