  • EXPEDITING FIELD CONVERGENCE OF FREQUENCY-TEMPERATURE MODEL OF RESONATOR OSCILLATORS USED IN TRANSCEIVERS
    Publication number: 20240030946
    Abstract: An aspect of the disclosure relates to a user equipment (UE) including: at least one antenna; a transceiver coupled to the at least one antenna, wherein the transceiver comprises: a resonator oscillator configured to generate a resonator signal; and a temperature sensor configured to generate a temperature signal related to a temperature of the resonator oscillator; an applications processor coupled to the transceiver; and a resonator field calibrator coupled to the applications processor and the transceiver.

  • Wireless chipset with a non-temperature compensated crystal reference
    Patent number: 10243569
    Abstract: An apparatus includes a temperature measuring device within a thermally conductive package. A crystal within the package is thermally coupled to the temperature measuring device and subjected to a same temperature as the temperature measuring device. A controller external to the package is configured to receive a signal from the crystal and a temperature measurement from the temperature measuring device. The controller is configured to estimate a frequency error of the crystal based on the temperature measurement and to provide a frequency error estimate to an external system.
