    摘要: A system for power supply synchronization in an Radio Frequency Identification (RFID) reader is shown and described. In one embodiment, the system includes one or more switched mode power supply devices and a signal generator. Each of the switched mode power supply devices provides power to at least one component of the RFID reader. The signal generator transmits a synchronization signal of a controlling frequency to each of the one or more power supply devices. In one embodiment, the system includes a signal processing unit that is configured to reject one or more spectral components from the output of the RFID reader.
