Multifunctional image sensor circuit

The invention relates to a multifunctional image sensor circuit. The photodiode array circuit comprises a plurality of photodiode circuits, a grading circuit system and a plurality of output circuits. Each of the plurality of photodiode circuits is coupled to receive a different one of the plurality of transmit control signals as an adjacent photodiode circuit adjacent in a first direction. The hierarchical circuitry is coupled to electrically connect the plurality of photodiode circuits into a group of photodiode circuit sense nodes in response to a hierarchical control signal. Each of the plurality of output circuits is coupled to one of the group of photodiode circuit sensing nodes. Each of the plurality of output circuits is coupled to receive the output charge from the photodiode circuit in the one of the group of photodiode circuit sense nodes and output an output signal to a bit line in response to the output charge and a row select signal. 本申请案涉及一种多功能图像传感器电路。光电二极管阵列电路包含多个光电二极管电路、分级电路系统及多个输出电路。所述多个光电二极
