Method and systems for amplifying an output of a CMOS pixel array

摘要

A CMOS sensor includes a pixel configured to output a voltage based on incident light received by the pixel. Circuitry is coupled to the pixel and is configured to determine a reset voltage of the pixel and to select a gain level based on the reset voltage of the pixel. A gain circuit is coupled to the circuitry and is configured to set a voltage level of the gain selected by the circuitry.

1. A CMOS sensor, comprising:
a pixel configured to output an analog signal in response to incident light received by the pixel; circuitry coupled to the pixel and configured to determine a reset voltage of the pixel in response to receiving the analog signal from the pixel, the circuitry further being configured to select a gain level based on the reset voltage of the pixel; and a gain circuit coupled to the circuitry and configured to amplify a digital data signal with the selected gain level.
