  • Patent number: 11619753
    Abstract: The disclosure provides a processing circuit adapted to read out a sensing voltage of an X-ray sensor and a signal processing method of a sampling circuit. The processing circuit includes an amplifier and the sampling circuit. An inverting input terminal of the amplifier is coupled to the X-ray sensor. The sampling circuit is coupled to an output terminal of the amplifier. The sampling circuit obtains a first voltage, a second voltage, and a sampling voltage of the X-ray sensor in different periods. The sampling voltage is between the first voltage and the second voltage.
