A system containing an ambient light and a proximity sensor with intrinsic ambient light rejection

A system for measuring ambient light as well as proximity of a reflective object is presented. A new technique of ambient light disturbance cancellation in proximity mode is proposed, enabling high accuracy measurements over a wide range of backlight. The chip, built in a 0.25μm CMOS technology, is...
