Abstract

A LiDAR system is disclosed that includes a SPAD unit array and J read group (RG) channels. The SPAD unit array is arranged in M rows and N columns of pixel read groups. Each row includes K pixel read groups. Each pixel read group outputs a detection signal in response to a light pulse that is incident on the pixel read group. Each RG channel corresponds to at least one row of pixel read groups and includes L time-to-digital converters that respectively generate timestamp information corresponding to detection event signals of each of L pixel read groups in the at least one row of pixel read groups in which J<M and L≤K. Each RG channel stores the timestamp information in an accumulator bin of a histogram circuit corresponding to a value of the timestamp information using hardwired addressing based on the value of the timestamp information.
