    Abstract: The present disclosure relates to a field-effect transistor (FET) controlling apparatus and method for accurately, controlling an operation state of a FET by adaptively adjusting a voltage applied to the FET to correspond to a voltage of a source terminal of the FET. The voltage applied to the gate terminal of the FET may be adaptively controlled according to the voltage of the source terminal using a capacitor. Therefore, even when the source terminal is not connected to the ground but connected to an external load, there is an advantage that the operation state of the FET may be smoothly and accurately controlled. In addition, there is an advantage that a voltage within a certain range may be applied to the gate terminal of the FET.
