1. A method comprising:

  • generating a current with a transmitter of an integrated circuit (IC) and coupling the current to an inductor via an input/output (I/O) terminal of the IC; and

    sensing information received at the IC through the inductor by sensing a variation in impedance seen at the I/O terminal, wherein sensing the variation in impedance comprises;

    sensing the current coupled to the inductor;

    converting the sensed current into a voltage; and

    sensing a variation in the voltage with a receiver.
