Abstract:
An image sensor includes a photoelectric converter to generate charges in response to incident light and to provide the generated charges to a first node, a transfer transistor to provide a voltage of the first node to a floating diffusion node based on a first control signal, a source follower transistor to provide a voltage of the floating diffusion node as a unit pixel output, a correlated double sampler (CDS) to receive the unit pixel output and to convert the unit pixel output into a digital code. The first control signal having first, second, and third voltages is maintained at the second voltage in a period between when the voltage of the first node is provided to the floating diffusion node and when the CDS is provided with the voltage of the first node as the unit pixel output.

Claim (Index 11):
An image sensor, comprising:\n a photoelectric converter to receive light, to generate charges in response to the received light, and to provide the generated charges to a first node; a transfer transistor connected to the first node and a floating diffusion node and including a gate terminal receiving a first signal through a transfer line; a source follower transistor connected to a second node and a first voltage source and including a gate terminal connected to the floating diffusion node; a select transistor connected to a pixel output terminal and the second node and including a gate terminal receiving a second signal; and a correlated double sampler (CDS) to receive an input from the pixel output terminal, wherein: the first signal has first, second, and third voltages having different voltage levels from one another, the first signal changes from the first voltage to the second voltage before the CDS receives the input from the pixel output terminal, and the first signal changes from the second voltage to the third voltage after the CDS receives the input from the pixel output terminal.
