Abstract:

This article presents a low-power (LP), compact, wideband (WB) low-noise transconductance amplifier (LNTA)-first receiver (RX) designed for software-defined radios (SDRs). It comprises the LNTA, frequency divider, mixer, and trans-impedance amplifier (TIA). The LNTA utilizes a common gate (CG)-common source (CS) structure without on-chip inductors and incorporates gm-boosting and …

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 …
