Abstract: A light receiving device includes: a pixel array unit that includes pixels that receive light; a first frequency generation unit; a time measurement unit that operates on the basis of a signal from the first frequency generation unit and outputs a digital code in accordance with a time difference between a timing of light emission from a light source and a timing of light reception by the pixels; a second frequency generation unit; and a selection unit that selectively supplies the time measurement unit with one of a signal from the pixels or a signal from the second frequency generation unit.

Abstract: A measurement apparatus (110A) according to an embodiment includes: a time-to-digital converter circuit (111) that measures a time period between an emission timing at which light is emitted from a light emitting unit (101) and a time point at which a light receiving unit (102) receives the light; a delay means (114A) that adds, to the time period measured by the time-to-digital converter circuit, a positive or a negative delay having a length that is different from a cycle of a clock used by the time-to-digital converter circuit and that is used as a unit amount of delay; and a storage unit (112) that stores therein time information that indicates the time period measured by the time-to-digital converter circuit and delay information that indicates an amount of delay to be added by the delay means, in association with each other, related to each of a case in which a delay is added by the delay means and a case in which a delay is not added by the delay means.

Abstract: The present technology relates to a phase locked loop and a control method therefor, which are capable of achieving low power consumption and good phase noise while suppressing the growth of circuit area.
