    Abstract: This application relates to a power supply matching circuit, an optical receiving assembly, and a photoelectric system. The power supply matching circuit is configured to convert a current signal of a photodetector array into a voltage signal, and the photodetector array includes a first photodetector and a second photodetector. The first photodetector includes a first cathode, a first anode, and a second cathode that are sequentially arranged. The second photodetector includes a third cathode, a second anode, and a fourth cathode that are sequentially arranged. The power supply matching circuit includes a first power electrode, a first ground electrode, a first radio frequency electrode, and a second radio frequency electrode. The first anode is electrically connected to the first radio frequency electrode, the second anode is electrically connected to the second radio frequency electrode, both the second cathode and the third cathode are electrically connected to the first ground electrode, and the fourth cathode is electrically connected to the first power electrode. In this application, a design of sharing the first ground electrode and the first power electrode greatly simplifies an electrode arrangement of the power supply matching circuit, and reduces design complexity.

    Abstract: A receiver circuit comprising: an input-pin; a receiver-input-node; a ground-pin; an internal-node that is connected to the input-pin; and a MOSFET. The MOSFET has a conduction channel connected in series between the internal-node and the receiver-input-terminal; and a gate terminal, the voltage at which sets the conductivity of the conduction channel. The receiver circuit also includes an amplifier that: has an input terminal that is connected to the internal-node; and provides a voltage control signal to the gate terminal of the MOSFET such that the voltage at the internal-node with respect to the ground-pin is constant.
