Abstract:
1. An imaging system, comprising: a plurality of image processing circuit channels having a substantially similar circuit topology to one another, wherein the plurality of image processing circuit channels are configured to receive a plurality of image sensor signals and to process the plurality of image sensor signals to generate a plurality of analog output signals; a plurality of proxy circuit channels having a substantially similar circuit topology to one another and to the plurality of image processing circuit channels, wherein the plurality of proxy circuit channels are configured to generate a plurality of analog proxy output signals associated with a common-mode noise of the plurality of image processing circuit channels, wherein the plurality of image processing circuit channels and the plurality of proxy circuit channels each comprise a differential amplifier, and wherein the plurality of analog output signals and the plurality of analog proxy output signals are generated in part by the differential amplifiers; a random noise reduction block configured to generate a common-mode noise reduction signal based on the plurality of analog proxy output signals; and a subtraction block configured to generate one or more output signals based on a difference between the common-mode noise reduction signal and one or more of the plurality of analog output signals.
