  • Patent number: 10215623
    Abstract: An optical sensor (10) includes a first switch (SW1) and a second switch (SW2), these switches are switched between a first step and a second step and thus the coupling of light receiving portions (photodiodes) and three analog-to-digital converters (ADCs) is switched. In the first step of the switch, photocurrents generated in a blue light receiving portion (BLUE), a green light receiving portion (GREEN) and a red light receiving portion (RED) are processed in real time. In the second step, photocurrents generated in an infrared light receiving portion (Ir), an environmental light receiving portion (CLEAR) and the green light receiving portion (GREEN) are processed. The photocurrents of the infrared light receiving portion (Ir) and the environmental light receiving portion (CLEAR) generated in the first step are calculated from a ratio of the two photocurrents measured in the green light receiving portion (GREEN).

  • Patent number: 10203526
    Abstract: A semiconductor junction may include a first layer and a second layer. The first layer may include a first semiconductor material and the second layer may be deposited on the first layer and may include a second material. The valence band maximum of the second material is higher than a conduction band minimum of the first semiconductor material, thereby allowing a flow of a majority of free carriers across the semiconductor junction between the first and second layers to be diffusive.

  • Patent number: 10161802
    Abstract: The present invention discloses a thermal pile sensing structure integrated with one or more capacitors, which includes: a substrate, an infrared sensing unit and a partition structure. The infrared sensing unit includes a first and a second sensing structure. A hot junction is formed between the first and the second sensing structures at a location where the first and the second sensing structures are close to each other. A cold junction is formed between the partition structure and the first sensing structure at a location where these two structures are close to each other. Another cold junction is formed between the partition structure and the second sensing structure at a location where these two structures are close to each other. A temperature difference between the hot junction and the cold junction generates a voltage difference signal. Apart of the partition structure forms at least one capacitor.
