摘要： A signal gain determination circuit including a digital comparator, a digital controller and an arithmetic module, and a signal gain determination method are provided. A sensing integration circuit generates a first count during a first integration time according to a first sensing signal. The digital comparator compares the first count and a predetermined count to generate a comparison result. The digital controller generates a control signal for indicating a signal gain to a signal amplifier of the sensing integration circuit according to the comparison result. The signal amplifier adjusts the first sensing signal according to the signal gain to generate a second sensing signal, so that the sensing integration circuit generates a second count corresponding to the second sensing signal during a second integration time. The arithmetic module generates an output count corresponding to the first sensing signal according to the second count and the signal gain.

摘要： A light sensor having a control complexity reducing mechanism is provided. When light is emitted to a photodiode by both of an ambient light source and a light-emitting component, a first coarse count value is counted by a counter and then is sampled and held by a first sample and hold circuit. When light is emitted to the photodiode by only the ambient light source, a second coarse count value is counted by the counter and then is sampled and held by a second sample and hold circuit. After the coarse count values are held, the counter performs a fine counting operation on light intensity of the light emitted by both of the ambient light source and the light-emitting component to generate a first fine count value, and on light intensity of the light emitted by only the ambient light source to generate a second fine count value.
