A correlated double-sampling circuit (150) for sampling an input signal received from a pixel sensor circuit (110) via an input line (COl_READ(X)). According to one embodiment, a first switch (M4) selectively couples a junction of first terminals of a first capacitor (Cl) and a second capacitor (C2) to the input line. A second switch (M5) selectively couples an output node coupled to a second terminal of the second capacitor (C2) to a reference voltage. A third switch (M6) selectively couples the output node to an output line (HSIG).
