Suppression of Row-Wise Noise in CMOS Image Sensors
摘要:
Embodiments of circuits and methods for suppressing row-wise noise in the analog domain in an image sensing device. In one embodiment, a pixel sampling circuit includes a readout circuit that is connected to a plurality of pixels to receive analog signals from the pixels. The pixel sampling circuit also includes a noise correction circuit that provides a reference signal to remove at least a portion of the noise in the analog signals received from the pixels before the analog signals are converted into digital signals.
