Amplifier circuit structure and method for controlling circuit

A method for controlling circuit, which is applied to an amplifier circuit structure comprising an amplifier, a first switch and a second switch;

• wherein
• the amplifier is located in a main path, an input end of the amplifier is a signal input end of the amplifier circuit structure, the first switch is located in a bypass;
• and
• one end of the 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 method comprising:
• controlling, by the first switch and the second switch, their respective operating states when a first instruction is received, so that the main path is connected to the signal input end of the amplifier circuit structure and the signal output end of the amplifier circuit structure;
• and
• controlling, by the first switch and the second switch, their respective operating states when a second instruction is received, so 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;
• wherein
• the amplifier circuit structure further comprises at least one phase compensation circuit;
• and
• the method further comprises performing phase compensation, with the at least one phase compensation circuit, for a phase difference caused when the main path and the bypass receive an input signal.
