Claim 3:
4. The amplifying circuit according to claim 1, wherein the second rectifying circuit further comprises the second band-pass filter and the second low-pass filter;
the second band-pass filter is connected between the second input terminal and the second rectifier, and is configured to perform a band-pass filtering on the second alternating current signal input from the second input terminal, and output a band-pass filtered signal to the second rectifier; and
the second low-pass filter is connected between the second rectifier and the differential amplifying circuit, and is configured to perform a low-pass filtering on the second pulsating direct current signal output from the second rectifier to output a second direct current signal.
