1. A method for operating a communications device that communicates via inductive coupling, the method comprising:
- obtaining a plurality of system or environmental parameters related to the communications device, wherein the system or environmental parameters comprise;
information regarding a transmitter voltage or a transmitter current from the communications device; and
information regarding a detuning condition in the communications device, wherein the information regarding the detuning condition comprises at least one of load information on a transmitter driver of the communications device and load information on an analog receiver of the communications device; and
adjusting a communications configuration of the communications device for communications via inductive coupling in response to the system or environmental parameters to control a load modulation amplitude (LMA) of the communications device to adjust a transmitter phase of the communications device, and to increase a signal-to-noise ratio (SNR) at a corresponding communications device.
