An imaging array of active pixel sensors uses a reset amplifier in each pixel in a four transistor CMOS implementation. 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. The ramp reset voltage is applied to all reset amplifiers of all pixels at the same time, thereby providing for reset of the entire array at the same time, i.e., global reset.
