  • Active load modulation transceiver
    Patent number: 10992504
    Abstract: In accordance with a first aspect of the present disclosure, an active load modulation (ALM) transceiver is provided, comprising a transmitter configured to send a transmit signal to an external device, wherein the transceiver is configured to adjust one or more parameters of the transmit signal at the end of at least one burst of said transmit signal. In accordance with a second aspect of the present disclosure, a method of operating an active load modulation (ALM) transceiver is conceived, comprising sending, by a transmitter of the transceiver, a transmit signal to an external device, and adjusting, by the transceiver, one or more parameters of the transmit signal at the end of at least one burst of said transmit signal.
    Type: Grant

  • Voltage converter
    Patent number: 9716443
    Abstract: A radio frequency transponder circuit, comprising: an AC-DC converter (70) connected to an RF input terminal (21a) and a DC output terminal (81) and operable to convert an RF signal (RFA) at the RF input terminal (21a) to a DC output signal (VDD) at the DC output terminal (81); and a voltage limiting circuit (50) connected to the RF input terminal (21a) and operable to limit the amplitude of the RF signal (RFA); wherein the voltage limiting circuit (50) comprises a NMOS limiting transistor (51) in parallel with a complimentary PMOS limiting transistor (52).
