Abstract
An image sensor includes a unit pixel, a first compensation circuit generating a first compensation voltage signal to compensate for horizontal noise corresponding to a variation in an input signal of a horizontal line coupled to the column line, a second compensation circuit generating a second compensation voltage signal to compensate for power noise corresponding to a variation in a power supply voltage, and a readout circuit including a first transistor, having a gate connected to an output terminal of the first compensation circuit, and a second transistor, connected to the first transistor in parallel, having a gate connected to an output terminal of the second compensation circuit, the readout circuit being configured to calibrate at least one of an output signal of the unit pixel and a ramp voltage signal, output by a ramp generator, using the first compensation voltage signal and the second compensation voltage signal.
