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.

Abstract: An image sensor includes a pixel array and an analog-to-digital (A/D) conversion unit. The pixel array generates an analog signal by sensing an incident light. The A/D conversion unit generates a digital signal in a first operation mode by performing a sigma-delta A/D conversion and a cyclic A/D conversion with respect to the analog signal and generates the digital signal in a second operation mode by performing a single-slope A/D conversion with respect to the analog signal. The image sensor provides a high-quality image in a still image photography mode and a dynamic image video mode.
