ABSTRACT:
An ambient light sensing circuit includes a transistor, a first storage capacitor coupled to the transistor and adapted to compensate for a threshold voltage of the transistor, a second storage capacitor coupled to the first storage capacitor, a photodiode coupled to the first storage capacitor and the second storage capacitor and adapted to change a coupling voltage of the first and second storage capacitors based on ambient light incident thereon, a first switch adapted to selectively apply the first power supply voltage to the output load coupled to the transistor, and a second switch coupled to a first electrode of the transistor and the output load, and adapted to allow a charge stored in the storage capacitor to be discharged through the transistor based on the coupling voltage of the first storage capacitor and the second storage capacitor.
