Abstract: The present application relates to a method of operating a capacitance sensing device comprises: calculating a difference of a raw data compared to one of the raw data received in a previous data frame; and performing a comparison calculation based on the raw data and a stored baseline value to determine whether a proximity event has occurred. Under the proximity event, selects one of several baseline value update procedures based on the magnitude of the difference. Thus, the present application effectively avoids the problem of failure to update the baseline value when the object is close to the capacitance sensing device for a long period of time, which may lead to misjudgment of the capacitance sensing device.

Abstract: A light sensor and control method thereof, which controls the light sensor comprising a first light emitted element, a second light emitted element, a first light sensing element and a control circuit. The light wavelength of the second light emitted element is greater than the light wavelength of the first light emitted element. The control circuit is coupled to the first and second light elements and the first light sensing element. When the display of an electronic device is in a light-up status, the control circuit switches on the first light emitted element to emit light; when the display of the electronic device is in a light-off status, the control circuit switches on the second light emitted element to emit light. Thus, it will prevent from the influence to the image of the display, and obtained the better sensing ability.

Abstract: The present application discloses a light sensor circuit comprising a first amplifier, a second amplifier and an active load. An integration circuit is formed by the operation of this light sensor circuit and connected to a photodiode. The cathode of the photodiode is controlled to maintain an identical or approximate voltage level with the anode of the photodiode, which significantly reduces the influence of the dark current from the photodiode. Consequently, when applied to an analog-to-digital conversion device, the light sensor circuit effectively maintains the performance and accuracy of the device. Additionally, this design significantly reduces circuit complexity and manufacturing costs.
