摘要：

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 mu m CMOS changes the pulse frequency from 50Hz in total darkness to 2MHz in extreme bright ambient at V-dd = 1V.
