Abstract: 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.

Abstract: This application provides decompression circuits. An example decompression circuit includes a plurality of sub-circuits. The sub-circuit includes a plurality of cellular automaton (CA) circuits and a phase shifter. Each of the plurality of CA circuits includes a first XOR circuit and a register. The first XOR circuit includes a first input end, a second input end, and an output end. A data input end of the register is coupled to the output end of the first XOR circuit. A data output end of the register is coupled to the first input end of the first XOR circuit and an input end of the phase shifter. The data output end of the register is further coupled to the second input end of the first XOR circuit in a different CA circuit. The phase shifter is configured to output a test signal.
