To provide devices for light detection and ranging based on a time of flight of light pulses comprising an array of single photon avalanche diodes (SPADs), in particular, such systems and methods that include a control device for receiving digital signals from a SPAD array and performing averaging processing.SOLUTION: The present disclosure relates to a system that includes a monolithic, single-chip receiver. The system includes: a plurality of macropixels, each made up of an array of SPADs; a plurality of pipelined adders communicatively coupled to respective portions of the plurality of macropixels. Operations of the system comprise: during a listening period, receiving, at each of the pipelined adders, photosignals from the plurality of macropixels; and providing an output that includes a series of frames that provide an average number of SPADs of the respective portions of the plurality of macropixels triggered during a given listening period.SELECTED DRAWING: Figure 1B
