Hybrid center of mass method (CMM) pixel

A Light Detection And Ranging (LIDAR) measurement circuit includes a control circuit configured to receive respective detection signals output from one or more single-photon detectors in response to a plurality of photons incident thereon. The control circuit includes a photon counter circuit including a digital counter circuit and an analog counter circuit, the digital counter circuit being responsive to an output of the analog counter circuit or the analog counter circuit being responsive to an output of the digital counter circuit to count detection of respective photons of the plurality of photons based on the respective detection signals, and a time integration circuit configured to output a time integration signal representative of respective times of arrival indicated by the respective detection signals. The control circuit is configured to calculate an estimated time of arrival of the plurality of photons based on a ratio of the time integration signal and the count of the detection of the respective photons of the plurality of photons.
