Time of flight-pixel, has monitoring circuit provided for monitoring charge amount in voltage at storage area and comprising devices for detecting charge amount in storage area and/or equivalent voltage or corresponding current

摘要

The pixel has a radiation-sensitive area (1), and two loads comprising connection contacts (11, 12) on an integrated semiconductor chip. A storage area for the loads is attached to the radiation-sensitive area, and a free charge carrier is formed in the radiation-sensitive area. A monitoring circuit (20) is provided for monitoring charge amount in the voltage at the storage area and comprises devices for detecting the charge amount in the storage area and/or an equivalent voltage or a corresponding current. Independent claims are also included for the following: (1) one or two-dimensional pixel array comprising a part of a pixel (2) a method for operating a time of flight-pixel.
