In contrast to a conventional histogram-based peak detection method, this letter proposes a mean detection method using a highly digitized phase-domain delta–sigma (PD\u0000<inline-formula> <tex-math>$Delta Sigma$ </tex-math></inline-formula>\u0000) TDC. The proposed TDC operates in an incremental \u0000<inline-formula> <tex-math>$Delta Sigma $ </tex-math></inline-formula>\u0000 manner for a compact implementation and utilizing a digital integrator as a loop filter that facilitates an extended counting, resulting in significantly improved resolution. By utilizing a dual gated-ring oscillator (GRO) structure, time-quantization noise due to a residue phase of GRO is effectively mitigated. To address the issue of single-photon avalanche diode (SPAD) signals due to their stochastic nature, a dual time window is proposed to compensate for counting error when SPAD trigger missing occurs.
