Abstract (in Japanese) (See Japanese page) 
(in English) This paper reports that the floating capacitor load readout operation has higher pixel signal readout gain and wider linear response range than conventional readout operation, and the reason. We fabricated the prototype chip which has 1140Hx768V pixels of 2.8 um pitch with 2 shared pixel technology and verified the effectiveness. When the power supply voltage is 2.0V, floating capacitor load readout operation increases readout gain by 8 % and enlarges linear response range by 47 % in comparison to conventional readout operation using column current source.
