Abstract
A method may include operating a single-photon avalanche diode (SPAD) in a first mode to determine a light intensity level associated with the SPAD, operating the SPAD in a second mode wherein a reverse bias voltage is applied in the second mode to bias the SPAD beyond its breakdown voltage, such that the SPAD operates in a detection mode, and determining a magnitude of the bias voltage applied to the SPAD in the second mode based on the light intensity level determined in the first mode.
