Abstract
A single capacitor (C) can be used for both readout and noise reduction in an imaging sensor. This dual-purpose use of the single capacitor is facilitated by a switching arrangement (Φ) which connects the capacitor to a low impedance node (n, n) during charge storage. The low impedance node is also used to drive a column readout line (V).
