There is provided, a method for clock recovery in a RFID tag, the method includes receiving a RF field from a RFID reader. A field clock is generated from the received RF field, from which a clock recovery signal is generated. The RF field is modulated to produce a RF modulation. Generation of the clock recovery signal is paused while the RF field is being modulated. A modulation envelope signal is generated and used for load modulation. Generation of the clock recovery signal at the end of the RF modulation is resumed after a delay of one clock cycle from a falling edge of the modulation envelope signal. In another embodiment of the method, instead of adding the delay, a differential amplifier is used to increase RF field detection sensitivity. The method and the RFID tag ensures synchronized resumption of a PLL clock and the clock recovery signal.
