An ODT circuit improving a high frequency performance using a separate driver is provided to compensate a parasitic capacitance component by operating a transistor simultaneously with an inductor, to improve a linear characteristic by maintaining impedance regularly. An ODT(On Die Termination) circuit improving a high frequency performance using a separate driver comprises the followings: a first driver(410) outputting a first control signal, and controlling an operation mode of an ODT operation by answering to an ODT enable signal; a second driver(430) outputting a second control signal, and controlling the operation mode of the ODT operation by transiting the ODT enable signal; a resistor(R) connected to an output terminal of a first and a second drivers; and a switch(450) determining the operation mode of the ODT operation, answering to the first control signal or the second control signal.
