Abstract
An output device for outputting an output signal. The output device comprises an amplifying unit and a control unit. The amplifying unit has a first input terminal, a second input terminal, and an output terminal outputting the output signal, wherein the amplifying unit is configured with a feedback loop. The control unit configures in the feedback loop and controlled by a control signal. The control unit turns off the feedback according to the control signal for a first period, and the control unit turns on the feedback according to the control signal after the first period.
