Patent number: 9743023Abstract: In an image sensor, a photo detector circuit applies a photo current to a capacitive node during a photo detection time interval. A front-end circuit comprises an input transistor having a control node that is coupled to the capacitive node. A switchable biasing arrangement puts the input transistor in a disabled state during the photo detection time interval. The input transistor is put in an enabled state after the photo detection time interval. This then causes the front-end circuit to provide an output signal that is representative of a voltage on the capacitive node after the photo detection time interval.Type: GrantFiled: January 26, 2015Date of Patent: August 22, 2017Assignee: UNIVERSITE CATHOLIQUE DE LOUVAINInventors: David Bol, Numa Couniot
