Abstract: Disclosed is an image sensor. Each of a plurality of pixels includes a photo diode, a transfer transistor connected between the photo diode and a floating diffusion node, a reset transistor connected between the floating diffusion node and a first power node to which a first power supply voltage is applied, a first source follower transistor including a gate connected to the floating diffusion node, a first terminal connected to a second power node to which a second power supply voltage is applied, and a second terminal connected to a first node, a precharge transistor connected between the first node and a floating node, a first precharge select transistor connected between the floating node and a ground node, a second precharge select transistor connected between the first node and a second node, and a first capacitor connected between a gate of the precharge transistor and the floating node.
