Abstract
A correlated double sampling (CDS) circuit may include a sampling circuit and a switching circuit. The CDS circuit may perform a CDS operation on a reset component of an input signal and an image component of the input signal based on a ramp signal, and the CDS circuit may generate an output signal. The switching circuit may include an auto-zero switch that connects a first input terminal receiving the input signal to an output node in response to an auto-zero control signal during an auto-zero interval. The switching circuit may connect a first terminal of the auto-zero switch to a reference voltage in order to cutoff a leakage current flowing to the auto-zero switch in response to a first boosting control signal during a first comparison interval and a second comparison interval. The output signal may be provided at the output node.
