Abstract:

Label-free miniaturized optical sensors can have a tremendous impact on highly sensitive and scalable point-of-care (PoC) diagnostics by monitoring real-time molecular interactions without any labels. However, current biophotonic platforms are limited by complex optical and external readout equipment, precluding their use in a PoC setting. In this work, we address …

A Compact Phase-Domain Delta–Sigma Time-to-Digital Converter With 8.5-ps Resolution for LiDAR Applications

A Compact Phase-Domain Delta–Sigma Time-to-Digital Converter With 8.5-ps Resolution for LiDAR Applications 150 150
Author(s): Yoondeok Na, Myung-Jae Lee, Youngcheol Chae

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 …
