Claim 9:
10. An amplification method applied to an amplifier, wherein
the amplifier comprises an amplification circuit, a power supplying circuit and an input circuit; wherein a first end of the amplification circuit is connected with a first end of the input circuit; a second end of the amplification circuit is connected with the power supplying circuit; and a third end of the amplification circuit is connected with a second end of the input circuit;
the method comprising:
supplying power, by the power supplying circuit, to the amplification circuit so that the amplification circuit operates in an amplification region;
obtaining an amplification gain in the case that the amplification circuit is in the amplification region, and amplifying, by using the obtained amplification gain, an input signal received by the input circuit;
wherein the input signal is a high-frequency signal; and
the input circuit comprises a first capacitor and a capacitive circuit, and one end of the first capacitor is connected with one end of the capacitive circuit;
the other end of the first capacitor is connected with the first end of the amplification circuit; the other end of the capacitive circuit is connected with the third end of the amplification circuit;
wherein the first capacitor is configured to filter the high-frequency signal to obtain an alternate current signal (AC signal) of the high-frequency signal;
the capacitive circuit is configured to determine an amplification gain of the high-frequency signal; and
correspondingly, the amplification circuit is configured to amplify the AC signal according to the amplification gain.
