An imaging array of active pixel sensors uses a compact three transistor CMOS implementation for each pixel. A current source at the top of each column creates a distributed feedback amplifier for each pixel in a selected row. The reset amplifier acts as a variable resistance in the source-follower amplifier feedback circuit. The variable resistance is controlled by a range reset voltage applied to the reset amplifier thereby nulling the photodiode reset noise.
