Abstract
An integrated circuit card receives power in the form of a radio frequency signal and includes a voltage generator that produces a first power supply voltage. The card also includes a voltage booster circuit for producing a high voltage that receives the first power supply voltage at a first supply input terminal. The voltage booster circuit also receives a second power supply voltage higher than the first power supply voltage at a second supply input terminal.
