  • Publication number: 20240380410
    Abstract: A channel selection circuit, an analog-to-digital converter (ADC) and a system-on-chip (SoC) are provided. During a sampling phase of an ADC circuit, a substrate voltage of a MOS switch in a selected channel is set to a voltage of analog input signal to which the channel is coupled. This eliminates the body-bias effect of the MOS switch, greatly improving linearity of the channel selection circuit and enabling the ADC to provide the required high speed and high-accuracy and exhibit excellent performance even at a low power supply voltage. Moreover, harmonic distortion around the dominant frequency can be suppressed, enabling the ADC to provide the required high accuracy (e.g., a 16-bit or even higher resolution).

  • Patent number: 11462143
    Abstract: An information processing method includes obtaining an area brightness adjustment instruction, and adjusting brightness of a first area of a display screen based on the area brightness adjustment instruction, so that the brightness of the first area is same as brightness of a second area of the display screen. The first area corresponds to a collection area of an image collection assembly. The image collection assembly senses light passing through the first area of the display screen to form an image. The first area is a partial area of the display screen. The second area is an area of the display screen excluding the first area.
