Claim 16:
17. A control method for an amplifying circuit, applied to an amplifying circuit connected with a target detection unit, the control method comprising:
when the amplifying circuit is in a first amplification phase, selecting, by a power supply output circuit, a second voltage value to output as a preset power supply signal according to a power supply switching signal, generating, by an isolation control circuit, an isolation control signal with the second voltage value according to a control command signal in a second state, and receiving, by the amplifying circuit, the isolation control signal and a signal to be processed and performing preliminary amplification on the signal to be processed; and
when the amplifying circuit is in an evolution phase, selecting, by the power supply output circuit, a first voltage value to output as the preset power supply signal according to the power supply switching signal, generating, by the isolation control circuit, an isolation control signal with the first voltage value according to the control command signal in the second state, and performing, by the amplifying circuit, secondary amplification on the signal to be processed according to the isolation control signal.
