  • Publication number: 20240113855
    Abstract: 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.

  • Publication number: 20240094335
    Abstract: Non-transitory computer-readable mediums and systems are provided in which a portion of each chirp of a series of chirps is held at an offset frequency for a period of time, and in which the offset frequency, the period of time or both is varied or dithered across the chirps of the series of chirps. The portion of a chirp that is held at an offset frequency for a period of time may be a non-active portion of the chirp, during which the chirp is not sampled. In some implementations, the portion of a chirp that is held at an offset frequency for a period of time is during a falling portion of the chirp, which may be at the beginning of the falling portion, or at the end of the falling portion immediately before a rise portion of a succeeding chirp.
