Abstract
An image sensor has an array of pixels read by column circuits to provide reset and read samples on a pair of sample capacitors. To alleviate the effects of parasitic capacitance in the region of the sample capacitors, a modified timing arrangement is used. Both sample switches are operated simultaneously to pre-charge both sample capacitors with a pixel signal value. One sample switch is operated after reset to apply a reset value to one of the pre-charged sample capacitors.
