PURPOSE: A mismatch modeling method of a capacitor is provided to measure mismatch of an MIM(Metal-Insulator-Metal) capacitor changing each rate or size, thereby modeling a rate and side of the capacitor according to a property of an analog circuit. CONSTITUTION: An analog circuit having a capacitor changing a rate or size is prepared and measures each mismatch value(304). A modeling parameter calculates a mismatch model according to the mismatch value and the rate or size of the capacitor and is extracted. A real capacitor mismatch value is calculated by applying the modeling parameter and a rate and size of the real capacitor for modeling to the mismatch model(308).
