Abstract:
This letter introduces a compact, high-resolution time-to-digital converter (TDC) for lidar applications. 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 $\Delta \Sigma$ ) TDC. The proposed TDC operates in an incremental $\Delta \Sigma $ manner for …
