Abstract
Exemplary embodiments are directed to adaptive signal scaling in NFC transceivers. A transceiver may include a programmable load modulation element configured for load modulation in a tag mode. Further, the transceiver may include a sensing element for measuring an amount of power harvested by the transceiver in the tag mode. The transceiver may also include a controller configured for adjusting a depth of load modulation of the programmable load modulation element depending on the amount of power harvested.
