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. In the readout period, the sampling circuit subtracts the second voltage from the sampling voltage to obtain a third voltage, subtracts the second voltage from the first voltage to obtain a fourth voltage, and divides the third voltage by the fourth voltage to read out the sensing voltage of the X-ray sensor.
