Summary:An image sensor and a method of operating the image sensor are disclosed. The image sensor includes: a first capacitor and a second capacitor; a first transistor between the photodiode and the floating diffusion node and receiving a transmission signal; a second transistor between the first power supply terminal and the floating diffusion node and receiving a reset signal; a third transistor between the second power supply terminal and the first node and having a gate connected to the floating diffusion node; a fourth transistor between the first node and the column line and receiving a precharge signal; a fifth transistor between the first capacitor and the feedback node and receiving the first sampling signal; a sixth transistor between the second capacitor and the feedback node and receiving a second sampling signal; a seventh transistor between the first node and the feedback node and receiving the first switching signal; and an eighth transistor between the floating diffusion node and the feedback node a
