    Abstract: An optical sensor includes a light receiving unit and a calculating unit. The light receiving unit includes a plurality of light receiving elements and a plurality of color filters. The plurality of light receiving elements include a first light receiving element and a second light receiving element through which a photocurrent flows when receiving light. The plurality of color filters include a yellow filter that covers a light receiving surface of the first light receiving element and a red filter that covers a light receiving surface of the second light receiving element. The calculating unit calculates an intensity of a yellow wavelength band based on a difference between a first output signal obtained from the photocurrent of the first light receiving element and a second output signal obtained from the photocurrent of the second light receiving element.

    Abstract: The present disclosure provides a semiconductor integrated circuit (IC) capable of suppressing influence of disturbance noise. The semiconductor IC includes an input terminal, an amplifier circuit, a first element and a second element. The input terminal is configured to allow inputting a signal of abrupt voltage change. The amplifier circuit is configured to amplify a difference between two input signals. The first element is connected to a first input end of the amplifier circuit. The second element is connected to a second input end of the amplifier circuit. In a plan view, a distance between a first position included in an arrangement region of the first element and a third position included in the input terminal is equal to a distance between a second position included in an arrangement region of the second element and the third position.
