  • Abstract
    A simple light-sensitive CMOS ring oscillator, the oscillation frequency of which depends on the chip ambient illumination, is presented. An experimental 21-stage ring oscillator fabricated in 0.5 μm CMOS changes the pulse frequency from 50 Hz in total darkness to 2 MHz in extreme bright ambient at Vdd=1 V
