BILDSENSOR MIT DYNAMISCHER LADUNGSBEREICHSABTASTUNG

摘要

An image sensor is disclosed. The image sensor includes: a pixel coupled to a floating diffusion region; a reset select transistor coupled between the floating diffusion region and a first supply voltage; an n-type source follower transistor coupled between the first supply voltage and a second supply voltage, the n-type source follower being operable to receive electrical signal from the floating diffusion region; an n-type row select transistor coupled between the first supply voltage and the n-type source follower transistor; a first sample-and-hold capacitor coupled between a third supply voltage and the second supply voltage; a first switch coupled between the n-type row select transistor and the first sample-and-hold capacitor; and a second switch coupled between the third supply voltage and the first sample-and-hold capacitor.
