An amplifier including a first transistor including a gate coupled to an input terminal and a grounded source; a load resistor provided between a drain of the first transistor and a power supply; an output terminal coupled to a node between the drain of the first transistor and the load resistor; a feedback path coupled to the input terminal and the output terminal and including a resistor and a capacitor; a bias voltage generator applying a gate bias voltage to the gate of the first transistor in response to an enable signal; a supply resistor provided between an output node for the gate bias voltage of the bias voltage generator and the gate of the first transistor; and an enable switch lowering a resistance value between the output node for the gate bias voltage and a node in the feedback path.
