Abstract
A circuit may include an array of single photon avalanche diode (SPAD) cells, each SPAD cell configured to be selectively enabled by an activation signal. The circuit may include a control circuit configured to selectively enable a subset of the array of SPAD cells based on a measured count rate of the array of SPAD cells.
