Abstract
Image sensors and methods for reading out image sensors. The image sensor includes a pixel array, a ramp generator, a gain circuit, a comparator, a digital counter, and a controller. The ramp generator is configured to generate a ramp signal. The gain circuit is configured to apply a first gain to the ramp signal when a pixel is reset and a selected gain to the ramp signal when the pixel is read out. The comparator is configured to compare a pixel output when the pixel is reset to the ramp signal. The comparator is also configured to compare the pixel output when the pixel is read out to the ramp signal. The digital counter is also configured to determine a digital signal value based on the outputs of the comparator. The controller is configured to determine a pixel value for the pixel based on the digital signal value.
