Abstract
For example, analog pixel circuitry may include a first input to input an analog pixel signal of the pixel; Sample and Hold (SH) circuitry to provide an analog sample of the pixel based on the analog pixel signal; one or more second inputs to input analog samples of one or more binning pixels, respectively; a plurality of capacitors having capacitor outputs connected to a common output terminal, wherein a capacitor input of a first capacitor is connected to an input terminal to input the analog sample of the pixel from the SH circuitry, wherein capacitor inputs of one or more second capacitors are connected to the one or more second inputs, respectively; and an amplifier configured to provide an amplified analog signal by amplifying an analog signal from the common output terminal.
