Abstract
An electronic module includes an ambient light sensor and a proximity sensor. The ambient light sensor includes an ambient light photodetector. The proximity sensor includes an infrared photoemitter, a reference infrared photodetector and another infrared photodetector. The ambient light sensor is arranged in a stack over the proximity sensor with a position that allows infrared photons transmitted by the infrared photoemitter to be received by the reference infrared photodetector.
