Abstract: Disclosed is a pixel sensor circuit including a photodiode element and a transistor element. The photodiode element is configured to sense an X-ray to generate a photocurrent signal. The photodiode element has a first end and a second end. A bias voltage is applied to the first end of the photodiode element. The transistor element is coupled to the second end of the photodiode element. The transistor element is configured to control the photocurrent signal to be read out. The voltage value of the bias voltage is adjusted according to the intensity of the X-ray.
