Patent abstract
An amplifier device includes an alternate current (AC) coupling circuit, an amplifier circuit, and a first bias circuit. The amplifier circuit is configured to amplify an input signal to generate an output signal, in which the amplifier circuit includes a first input terminal, and the first input terminal receives the input signal via the AC coupling circuit. The first bias circuit is configured to apply a first bias voltage to the first input terminal according to one of the output signal and a first voltage, such that the amplifier circuit amplifies the input signal to output the output signal.
