  • SINGLE-ENDED TO DIFFERENTIAL SIGNAL CONVERTER, AND SIGNAL CONVERTING METHOD
    Publication number: 20230246635
    Abstract: It is described a signal converter device (100) for converting a single-ended signal to a differential signal, the device (100) comprising: i) a multiplier device (110), configured to receive a single-ended incoming signal (105), and multiply the incoming signal (105) to provide a multiplied signal (115); and ii) a divider device (120), configured to receive the multiplied signal (115), and divide the multiplied signal (115) to provide a differential signal (125a, 125b). Further, a corresponding signal conversion method is described.

  • RF transceiver
    Patent number: 10346732
    Abstract: A RF transceiver for RF communication with a further RF transceiver is described. The RF transceiver comprises a RF transmitter; a clock generator coupled to the RF transmitter, the clock generator comprising a crystal oscillator circuit including an amplifier, a distance monitor configured to monitor the distance between the RF transceiver and the further RF transceiver; a controller coupled to the distance monitor and the clock generator. The controller is configured to vary the crystal oscillator swing amplitude dependent on the distance between the RF transceiver and the further RF transceiver.
