Abstract: An internal voltage generator of a contactless IC card includes a regulator, an internal voltage generating unit, a reference voltage generator, and a switching unit. The regulator generates a first internal voltage based on an input voltage and a first reference voltage received through an antenna. The internal voltage generating unit generates a second internal voltage used as power in an internal circuit based on the first internal voltage. The reference voltage generator generates a second reference voltage independent of a variation component that can be generated in the first internal voltage based on the first internal voltage. The switching unit provides one among the second reference voltage and the first internal voltage as the first reference voltage in response to first and second switching control signals based on an operation mode of the internal circuit.
