Original Abstract Submitted
This application provides a photoelectric amplification circuit and a signal processing method. The photoelectric amplification circuit includes a first photodiode and a second photodiode that are connected in parallel. A Doherty circuit structure is used, so that power supply efficiency of the photodiode in a back-off state can be improved. In addition, an impedance modulation unit is used, to implement dynamic load conversion from a back-off point to a maximum output point. This helps maintain high output efficiency of the first photodiode and the second photodiode in an interval between the maximum power point and the back-off point.
