Abstract
A load modulation device in a remotely powered integrated circuit includes an oscillating circuit, and a voltage device for regenerating first and second power supply voltages. The voltage device includes at least one MOS transistor in a well on at least one terminal of the oscillating circuit. The at least MOS transistor includes a source or drain connected to the at least one terminal. A bias circuit biases the well to the first or second power supply voltage based upon a modulation signal.
