Abstract

A triple-junction RGB optical sensor with vertically stacked photodiodes and signal processing that provides precise values of the currents generated by blue, green, and red light is presented. The signal processing is based on the determination of the border depths of the space-charge regions of all three photodiodes. A current-mode implementation using current conveyors and variable-gain current amplifiers is introduced. The responsivities of all three photodiodes calculated using the proposed approach are in very good agreement with the measured results.
