Document Type and Number:
Japanese Patent JP7422133
Kind Code:
B2
Abstract:
In a solid-state image sensor provided with a comparator that compares a reference signal and a pixel signal, the image quality of image data is improved.A voltage divider circuit supplies a divided voltage of an input voltage and a predetermined reference voltage that are input. An input-side differential transistor outputs a drain current corresponding to the gate-source voltage between the divided voltage input to the gate and a predetermined source voltage. An output-side differential transistor outputs a voltage corresponding to the drain current as a result of comparison between the input voltage and the reference voltage. A control transistor reduces the gate-source voltage in a case where the input voltage is out of a predetermined range.
