Abstract

See full text

High resolution tuning of the phase for active load modulation (ALM) in a near field communication (NFC) system is desirable for optimizing the load modulation amplitude. The present disclosure describes that, in one embodiment, high resolution tuning of the phase can be achieved by adjusting the attenuation factor of a radio frequency (RF) attenuator in the NFC system.
