摘要：
Systems and methods for fixed pattern noise reduction in image sensors is disclosed herein. An example method may include simultaneously providing a pixel reference voltage of a pixel to a reference sampling capacitor and a signal sampling capacitor, decoupling the reference sampling capacitor from the pixel, providing a signal voltage to the signal sampling capacitor, and decoupling the signal sampling capacitor from the pixel.
