Abstract: An RFID reader, comprising a high-efficiency Class-C power amplifier having an input, an output, and a supply voltage, a modulator coupled to the supply voltage of the Class-C power amplifier, and an RF carrier signal coupled to the input of the Class-C power amplifier. The modulator changes the supply voltage of the Class-C power amplifier resulting in highly controlled amplitude modulation of the RF carrier signal at the output of the Class-C power amplifier.

Abstract: A method for use in a RFID reader, the method comprising providing an output signal from an amplifier of a transmitter, attenuating the output signal via a step attenuator, detecting and comparing the attenuated output signal to a reference value, and adjusting power to the amplifier until the attenuated output signal is substantially equal to the reference value. The attenuated output signal drives a local oscillator signal of a receiver thereby canceling noise generated by the transmitter in the receiver.

A speed of the RFID tag is determined based, at least in part, on the determined phase for the sampled signal for each of the plurality of different times.
