Abstract:
There is provided a light receiving device including: a pixel including a first tap configured to detect a charge photoelectrically converted by a photoelectric conversion unit, and a second tap configured to detect a charge photoelectrically converted by the photoelectric conversion unit; a first comparison circuit configured to compare a first detection signal detected by the first tap and a reference signal; a second comparison circuit configured to compare a second detection signal detected by the second tap and the reference signal; a first zero reset signal generation circuit configured to generate a first zero reset signal that is supplied to the first comparison circuit when the first comparison circuit performs an auto zero operation; and a second zero reset signal generation circuit configured to generate a second zero reset signal that is supplied to the second comparison circuit when the second comparison circuit performs an auto zero operation.
