Abstract
An amplification circuit includes a first amplifier circuit and a second-stage amplifier. The second-stage amplifier is connected to the amplifier to form a multi-stage amplification circuit. The first amplifier circuit includes a first-stage amplifier and a bypass circuit. The bypass circuit includes a first transistor. A first end of the first transistor is coupled to the input end of the first amplifier circuit, a second end of the first transistor is coupled to the output end of the first amplifier circuit, and a third end of the first transistor is coupled to a supply voltage. The first end of the first transistor is further coupled to a first control terminal to receive a control signal for controlling a bias voltage of the first transistor, so as to make the amplification circuit work in different operation modes.
