Title:
LOW-GAIN LOW-BANDWIDTH CHARGE AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2021/145121
Kind Code:
A1
Abstract:
An image sensor and processing method therein comprises a pixel circuit configured to generate a pixel signal; a vertical signal line configured to convey the pixel signal; and a charge amplifier circuit configured to receive the pixel signal, the charge amplifier circuit being switched between a low bandwidth state and a high bandwidth state in response to a control signal.
