Title:
LIGHT RECEPTION DEVICE AND DISTANCE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/149173
Kind Code:
A1
Abstract:
This light reception device comprises: light reception elements (10001-1000n) that each produce a current corresponding to an incident photon in a state in which a prescribed voltage is being applied thereto and are restored to a pre-incidence state by a recharging current; a generation unit (1100a) for generating a reference current; and replication units (10011-1001n) for generating replicated reference currents by replicating the reference current generated by the generation unit. The light reception elements have recharging currents based on the replicated reference currents supplied thereto.
