Full-frame image sensor system

A full-frame image sensor system, which is integrated in a chip, comprising:

• a pixel array, at least a pair of readout circuits, at least a pair of channel selection circuits, at least a pair of interface circuits and a control circuit, at least a pair of power input-output interfaces and at least a pair of auxiliary circuits;
• wherein taking the pixel array as the center, the readout circuits, the channel selection circuits and the interface circuits are symmetrically arranged on two sides of the pixel array respectively, so that the center of the pixel array coincides with the center of the entire chip;
• the readout circuits are electrically connected to the pixel array from the two sides of the pixel array respectively;
• the channel selection circuit and the readout circuit on the same side of the pixel array are electrically connected to each other;
• the interface circuit and the channel selection circuit on the same side of the pixel array are electrically connected to each other;
• wherein the pixel array is used for detecting an image signal and outputting the image signal to the readout circuits;
• the readout circuits are used for receiving the image signal from the pixel array, amplifying the image signal, converting the amplified image signal into a digital signal, and then outputting the digital signal to the channel selection circuit;
• the channel selection circuit is used for amplifying the digital signal and then performing selective transmission;
• the interface circuit is used for outputting the digital signal to the outside interface;
• the control circuit is connected to the readout circuit, the channel selection circuit and the interface circuit, and is used for controlling the transmission and working time sequence of each circuit;
• the power input-output interfaces are respectively arranged above and below the pixel array, and is used for inputting or outputting a power signal of each circuit;
• the auxiliary circuits are arranged above and below the pixel array respectively, and are used for providing a reference voltage and a reset voltage for the whole circuit.
