    Abstract: The present invention provides a pixel circuit. A first S/H stage and the second S/H stage are connected in cascade between a buffer amplifier and an amplifier circuit. During a first and a second time period, a buffered output signal having a first voltage and a second voltage generated by the buffer amplifier are stored serially to the first S/H stage and the second S/H stage. The amplifier circuit senses the first voltage and the second voltage stored in the first S/H stage and the second S/H stage independently for generating a first output signal and a second output signal correspondingly. A calibrated signal is generated according to the first output signal and the second output signal.
