Abstract
A combining network for an array of SPAD devices includes: synchronous sampling circuits, wherein each synchronous sampling circuit is coupled to an output of a corresponding SPAD device and is configured to generate a pulse or an edge each time an event is detected; and a summation circuit coupled to an output of each of the synchronous sampling circuits and configured to count a number of pulses or edges to generate a binary output value.
