  • Patent number: 10477126
    Abstract: A pixel cell and readout circuit includes an anti-eclipse voltage clamp circuit at both the top and bottom of each column line of an array of the pixel cells. The anti-eclipse voltage clamp circuits form a row with each column in the array coupled to an anti-eclipse voltage clamp circuit. The combination of two rows of anti-eclipse voltage clamp circuits helps settle the clamp voltage more rapidly and to compensate for the increased length of the anti-eclipse voltage circuit row as well as the column line resistance due to narrow metal lines and increased numbers of pixels as well as the requirement to operate a sensor at a higher frame rate. More significantly this circuit construction can minimize vertical shading in the resulting image.

  • Patent number: 10171760
    Abstract: A solid-state imaging device where when the charge from a photodiode PD11 is small, all of the charge is transferred to the feedback capacitor to obtain an output voltage amplified with a high gain due to a mirror effect created by a CTIA circuit including an amplifier arranged in a readout circuit and a feedback capacitor, while when the CTIA circuit is saturated, due to automatic reduction of the mirror effect, the remaining excessive charge is moved to a floating diffusion FD11 having a larger capacitance to obtain an output voltage amplified with a low gain and where the obtained voltage is simultaneously output from the pixel and taken into a column sampling circuit. Due to this, a low-luminance signal can be read out with a high gain, a high-luminance signal can be read out with a low gain suppressing saturation, and in addition, signals of a high gain and low gain can be obtained by two reading operations. Further, it becomes possible to improve the lowest object illuminance performance.
