  • Patent number: 8416326
    Abstract: 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.

  • Patent number: 7804535
    Abstract: In a solid-state imaging device meeting color image pickup, which an AD converter is mounted on the same chip, the circuit scale and the number of transmission signal lines are reduced and a reference signal suitable for color image pickup is fed to an AD conversion comparing portion. DA converter circuits for two pixels of a repeat unit of a separation filter in the horizontal row direction in a unit of readout are prepared as a functional portion to generate a reference signal for AD conversion. The DA converter circuits generate the reference signals having a tilt in accordance with a color property and varying from an initial value based on a non-color property such as a black reference and a circuit offset. Each reference signal independently outputted from the DA converter circuits is basically directly transmitted through common signal lines to a voltage comparing portion which corresponds to color filters having a common color property through independent signal lines.

  • Patent number: 7683818
    Abstract: A column analog-to-digital converter having a voltage comparator and a counter is arranged for each a vertical signal line. The voltage comparator compares a pixel signal inputted via the vertical signal line at each row control signal line with a reference voltage, thereby generating a pulse signal having a length in time axis corresponding to the magnitude of a reset component and a signal component. The counter counts a clock to measure the width of the pulse signal until the end of the comparison operation of the comparator, and stores a count at the end of the comparison. A communication and timing controller controls the voltage comparator and the counter so that, in a first process, the voltage comparator performs a comparison operation on a reset component with the counter performing a down-counting operation, and so that, in a second process, the voltage controller performs the comparison operation on a signal component with the counter performing an up-counting operation.
