Image sensor capable of cancelling offset voltage of semiconductor device included therein |
摘要 |
An image sensor includes: a pixel unit that outputs a first signal including an offset voltage inherent to a pixel; a CDS unit that performs correlated double sampling of a second signal that is obtained from the first signal by canceling the offset voltage inherent to the pixel, and outputs the second signal after the correlated double sampling as a third signal including an offset voltage due to the CDS unit; and an ADC unit that performs analog-to-digital conversion of a fourth signal that is obtained from the third signal by canceling the offset voltage due to the CDS unit.
