Abstract
An actuator of a camera module includes a driving coil disposed to face a detection target; a driving circuit including a plurality of transistors connected to the driving coil; and a processor configured to provide a respective gate control signal to a gate of each of the plurality of transistors, and detect a displacement of the detection target based on a component of an oscillation signal generated in a driving signal applied to the driving coil in response to an operation of any one of the plurality of transistors being switched by the respective gate control signal.
