New SPAD detector design improves direct time-of-flight measurement accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method to improve the accuracy of direct time-of-flight (dToF) measurements by utilizing perimeter-gated single-photon avalanche diode (SPAD) detectors. This technique aims to reduce errors caused by system-level and circuit-level timing jitters, as well as device-level uncertainty from dark noise. The study includes a framework for estimating dToF jitters and analyzes a counter-based time-to-digital converter circuit. Experimental results using a perimeter-gated SPAD (pg-SPAD) fabricated in a standard CMOS process demonstrate enhanced measurement accuracy in both free-running and time-gated operations. AI

IMPACT This research could lead to more precise sensor technologies, potentially impacting AI applications that rely on accurate depth perception and ranging.

    Direct Time-of-Flight Measurement Accuracy Improvement With Perimeter-Gated SPADs

    arXiv:2607.02546v1 Announce Type: cross Abstract: Direct time of flight (dToF) measurements are susceptible to errors because of system-level and circuit-level timing jitters. In addition, device-level uncertainty stemming from the dark noise of single-photon avalanche diode (SPA…
