Embodiments of the present invention employ a charged-based readout circuit in an image sensing system that includes a column readout circuit which may perform sampling on signals received from a pixel array and transfer a corresponding correlated double sample (CDS) signal, a differential channel readout circuit that may receive the corresponding CDS signal and amplify the signal using an output amplifier, and an output buffer which may receive the amplified CDS signal and output a corresponding signal out of the system. The output amplifier may be composed of two output amplifier paths so that ping-ponging is possible.
