Pixel circuit for converting an optical signal into an electric signal comprising a storage circuit storing charge output from an amplifying circuit, and drive method thereof, and detector using the same
Embodiments of the present disclosure provide a pixel circuit and a drive method thereof, and a detector including the pixel circuit. The pixel circuit includes a photoelectric conversion circuit, a reset circuit, an amplifying circuit, a first control circuit, a second control circuit, a storage circuit, and an output circuit. The photoelectric conversion circuit is configured to convert an optical signal into an electric signal. The reset circuit is configured to reset a voltage of the first node. The amplifying circuit is configured to amplify the voltage of the first node. The first control circuit is configured to control a voltage of the second node. The second control circuit is configured to control a voltage of the third node. The storage circuit is configured to store an electric charge corresponding to the voltage outputted from the amplifying circuit. The output circuit is configured to output the stored electric charge.
