Abstract
A NFC enabled device to couple inductively to the H field of an RF signal and a regulator to regulate a voltage derived from an RF signal inductively coupled to the inductive coupler. The regulator has at least one voltage controlled impedance having a switch on voltage. A regulator controller provides a control voltage to each voltage controlled impedance such as that the control voltage is not less than the switch on voltage of the voltage controlled impedance.
