    Abstract: An electronic circuit includes a unit pixel, a first clamp circuit, and a second clamp circuit. The unit pixel outputs a voltage having an output voltage level at a first output voltage level in a first time interval and at a second output voltage level in a second time interval different from the first time interval. The first clamp circuit is configured to clamp the output voltage level from the unit pixel to a first voltage level responsive to the first output voltage level being not greater than the first voltage level in the first time interval. The second clamp circuit is configured to clamp the output voltage level from the unit pixel to a second voltage level responsive to the second output voltage level being not greater than the second voltage level in the second time interval.

    Abstract: Disclosed is an image sensor device which includes a pixel that outputs a first pixel signal to a first column line during a first time period and outputs a second pixel signal to the first column line during a second time period, and a clamp circuit that outputs a first clamp signal to the first column line during the first time period. During the first time period, a voltage of the first column line is determined based on the first pixel signal and the first clamp signal. The pixel operates based on a first power supply voltage, and the clamp circuit operates based on a second power supply voltage lower than the first power supply voltage.

    Abstract: Disclosed is an image sensor including a pixel array including a plurality of pixels, each of the pixels including a first photodiode and a second photodiode, each of which outputs a first pixel signal based on a first conversion gain using the second photodiode in a first period, outputs a second pixel signal based on a second conversion gain using the second photodiode in a second period, outputs a third pixel signal based on the first conversion gain using the first photodiode in a third period, and outputs a fourth pixel signal based on the second conversion gain using the first photodiode in a fourth period, an ADC circuit that performs sampling on a reset signal and an image signal of each of the first to fourth pixel signal. A sampling count and the number of sampling bits are adjusted differently from each of the first to fourth period.
