Abstract
A method of wireless communication, with a circuit that includes a radio frequency identification (RFID) reader, can be carried out using a circuit that is configured and arranged to communicate with RFID cards that use load modulation of an RF carrier provided by the RFID reader. A presence of the radio frequency (RF) carrier is detected on an antenna. A local clock signal is generated. A difference between the local clock signal and the RF carrier is detected. In response to the detected difference, the frequency of the local clock signal is modified to reduce the detected difference. Load modulation of the RF carrier is mimicked by modulating the local clock signal to encode data; and driving the antenna with the modulated local clock signal.
