Patent number: 8416326Abstract: An NchMOS transistor Q71 on the input side of a current mirror 70 is made function as a voltage operating-point setting portion so that a pixel signal line potential (voltage of a horizontal signal line 20) would be constantly stable nearly at the GND. Then, an amplification factor and linearity become good in an amplification transistor in the solid imaging device 3. A current copier 90 is made function as a current sampling portion so as to receive a signal current IIN of the solid imaging device 3 through the current mirror 70 to carry out sampling of a pixel signal in a resetting period in the shape of current component as the pixel signal is. Calculating differential between a current component in a detecting period and an offset current, which is the current component in a resetting period in sampling, allows an offset component included in the pixel signal to be removed and only pure signal Isig to be picked up at an output terminal Iout, so that the FPN restraining function can be fulfilled.Type: GrantFiled: February 25, 2011Date of Patent: April 9, 2013Assignee: Sony CorporationInventors: Ken Koseki, Tsutomu Haruta, Yukihiro Yasui, Yasuaki Hisamatsu

Patent number: 8004590Abstract: From a pixel array where imaging pixels are arranged, pixel signals of respective columns on a selected row are read in parallel in a horizontal blanking period of a horizontal period. The pixel signals of the respective columns are output to horizontal signal lines in an effective period of the horizontal period via charge integrating amps provided respectively for the columns, i.e., provided respectively for vertical signal lines, and are thereby transferred horizontally. In the charge integrating amps, it is possible to enter a standby state while holding the pixel signals by a holding voltage. Furthermore, in the charge integrating amps, a reference potential for precharging feedback capacitors for amps at the time of a reading operation is automatically controlled based on a black level. Furthermore, pixel signals from the respective charge integrating amps are horizontally transferred in parallel using a plurality of horizontal signal lines.Type: GrantFiled: January 11, 2010Date of Patent: August 23, 2011Assignee: Sony CorporationInventors: Ken Koseki, Tsutomu Haruta
