US Patent 11482977 Amplifier circuit structure and method for controlling circuit

An amplifier circuit structure can include an amplifier located in a main path, and a first switch located in a bypass. One end of a second switch is a signal output end of the amplifier circuit structure, and the other end of the second switch is configured to selectively connect to a signal output end of the bypass or a signal output end of the main path. The first and second switches are configured to control their respective operating states when a first instruction is received, such that the main path is connected to the signal input end and the signal output end of the amplifier circuit structure; and to control their respective operating states when a second instruction is received, such that the bypass is connected to the signal input end of the amplifier circuit structure and the signal output end of the amplifier circuit structure.
