Abstract
A pixel circuit of an image sensor includes a sense node for storing a charge transferred from one or more photodiodes, a source follower transistor having its gate coupled to the sense node and its source node coupled to an output line of the pixel circuit via a read transistor, wherein a body contact of the source follower transistor is connected to the output line.
