Abstract
A correlated double sampling (CDS) circuit included in an image sensor includes a sampling unit and a timing controlled band-limitation (TCBL) unit. The sampling unit is configured to generate an output signal by performing a CDS operation with respect to a reset component of an input signal and an image component of the input signal based on a ramp signal, the input signal being provided from a pixel array included in the image sensor. The TCBL unit is connected to the sampling unit, and is configured to remove noise from the output signal based on a timing control signal. The timing control signal is activated during a first comparison duration, in which a first comparison operation is performed with respect to the ramp signal and the reset component of the input signal, and during a second comparison duration, in which a second comparison operation is performed with respect to the ramp signal and the image component of the input signal.
