Summary:An image sensor including: first and second capacitors; a first transistor between a photodiode and a floating diffusion node, and receiving a transfer signal; a second transistor between a first power terminal and the floating diffusion node and receiving a reset signal; a third transistor between a second power terminal and a first node and having a gate connected to the floating diffusion node; a fourth transistor between the first node and a column line and receiving a precharge signal; a fifth transistor between the first capacitor and a feedback node and receiving a first sampling signal; a sixth transistor between the second capacitor and feedback node and receiving a second sampling signal; a seventh transistor between the first node and feedback node and receiving a first switch signal; and an eighth transistor between the floating diffusion and feedback nodes and receiving a second switch signal.
