Abstract: The present invention relates to an internal voltage generation circuit of a smart card performing fingerprint authentication, which includes a mode detector, a switched capacitor circuit, and a low voltage drop regulator. The mode detector generates a mode signal indicating one of a contact mode in which the smart card provides an input voltage in direct contact with an external card reader and a non-contact mode in which the smart card provides the input voltage without contact with the card reader. Based on a rectified voltage rectified from the input voltage, the switched capacitor circuit generates a first drive voltage and a second drive voltage lower in voltage level than the first drive voltage. The low voltage drop regulator includes an error amplifier. Based on the mode signal, the low voltage drop regulator generates an error voltage by driving the error amplifier with the second drive voltage and generates a first output voltage by regulating the second drive voltage based on the error voltage in the contact mode and generates the error voltage by driving the error amplifier with the first drive voltage and generates the first output voltage by regulating the second drive voltage based on the error voltage in the non-contact mode.
