Abstract: An active circuit includes an active element, an input unit, and a bypass unit. The active element is coupled to an output terminal of the active circuit for outputting an output signal. The input unit is coupled to an input terminal of the active circuit, and is coupled to an input terminal of the active element through a node. The input unit adjusts a capacitance value of the input unit according to a first control signal. The bypass unit is coupled to an output terminal of the input unit through the node, and is coupled to the output terminal of the active circuit. The bypass unit turns on or off a signal bypassing path according to a second control signal.
