LOW-COST READOUT MODULE FOR LIDAR SYSTEM

Techniques and apparatuses are described that implement a low-cost readout module for a lidar system. The low-cost readout module includes a timing readout path and an intensity readout path, which are coupled to a receive channel of a receiver of the lidar system. The timing readout path generates time-sensitive information using a threshold-triggered timing circuit, which includes a time-to-digital converter. The intensity readout path generates non-time-sensitive information using a hold-and-sample circuit, which includes a hold circuit and an analog-to-digital converter. By utilizing the threshold-triggered timing circuit to provide time-sensitive data and the hold-and-sample circuit to provide non-time-sensitive information, the readout module can have a lower cost than other readout modules that utilize a high-performance analog-to-digital converter for each receive channel. 描述了实现用于激光雷达系统的低成本读出模块的技术和装置。低成本读出模块包括计时读出路径和强度读出路径，该计时读出路径和强度读出路径耦合至激光雷达系统的接收信道。计时读出路径使用阈值触发的计时电路生成时间敏感性信息，该阈值触发的计时电路可以包括时间数字转换器。强
