摘要

采用标准的0.35um HV CMOS技术实现了用于脉冲激光飞行时间测距应用的单芯片接收器。它包括一个9×9 SPAD阵列和一个10通道时间-数字转换器，单次射击精度为10ps。可选择任意3×3子阵列进行同时测量。所选的SPAD阵列可以门控，仅在选定的时间窗口内工作，以抑制黑暗和背景光引起的计数。在激光雷达环境下的功能测试表明，在近80米的范围内功能齐全。

A single chip laser radar receiver with a 9×9 SPAD detector array and a 10-channel TDC

A single chip receiver for pulsed laser time-of-flight rangefinding applications has been realized in a standard 0.35um HV CMOS technology. It includes a 9×9 SPAD array and a 10-channel time-to-digital converter with 10ps single shot precision. Any of the 3×3 sub-arrays can be selected for simultaneous measurement. The selected SPAD array can be gated to be operative only within a selected time window in order to suppress dark and background light induced counts. Functional tests in a laser radar environment indicate full functionality over a range of nearly 80 metres.
