Low Fixed Pattern Noise Current-mode Imager Using Velocity Saturated Readout Transi tor Abstract This paper described a novel current-mode active pixel sensor (APS) imager. Conversion of photodiode voltage to output current is done using transistors operating in velocity saturation region. The high output impedance
