Patent ID: 8433255

Claim:
A wireless communication element, comprising: a receive path configured to receive a first wireless communication signal and convert the first wireless communication signal into a first digital signal based at least on an oscillator signal; a transmit path configured to convert a second digital signal into a second wireless communication signal based at least on the oscillator signal and transmit the second wireless communication signal; and an oscillator configured to output the oscillator signal to at least one of the receive path and the transmit path, the oscillator comprising: a resonator; a temperature sensor configured to output a temperature signal indicative of an ambient temperature of the oscillator; a temperature compensation calculator configured to, based on the temperature signal, output a temperature-based frequency compensation signal; a frequency estimator configured to, based on a detected approximate frequency of operation of the oscillator, output a frequency estimation signal; a process compensation calculator configured to, based on the frequency estimation signal, output a process-based compensation signal that is based on a ratio of an actual frequency variation indicated by the frequency estimation signal to an expected frequency variation in the absence of process-dependent frequency variation; a control module configured to, based on the temperature-based frequency compensation signal and the process-based compensation signal, output a control signal; and a variable capacitor coupled to the resonator, a capacitance of the variable capacitor established based on the control signal.
