Document Type and Number:
WIPO Patent Application WO/2021/169240
Kind Code:
A1
Abstract:
An amplifier and an amplification method. The amplifier comprises an input circuit (101), an amplification circuit (102), and at least two feedback circuits (103a-103n); the input circuit (101) is connected to the input end of the amplification circuit (102); the output end of the amplification circuit (102) is separately connected to the first ends of the feedback circuits (103a-103n); the second ends of the feedback circuits (103a-103n) are separately connected to the input circuit (101); the input circuit (101) is configured to receive an input signal and a feedback signal; the amplification circuit (102) is configured to amplify the input signal and the feedback signal and obtain an amplified signal; the feedback signal is a signal obtained after at least part of the amplified signal is fed back to the input circuit (101) by means of a target feedback circuit; the target feedback circuit is a feedback circuit determined from that at least two feedback circuits (103a-103n) according to the type of the input signal.
