  • Abstract
    We demonstrate the first array of asynchronous event pixels that react to temporal color contrast of three different color spectra. The three different spectra are transduced into photo currents by stacked photo diodes. Temporal changes of the contrast of these three spectra are quantified as pulse density modulated signals and conveyed off-chip by the Address Event Representation (AER) protocol. The 16 × 16 pixel array has been fabricated in the standard TSMC 90nm CMOS process.
