    Abstract: A method may include measuring a frequency difference between an actual frequency and an expected frequency associated with a frequency control calibration signal value for each of a plurality of frequency control calibration signal values during a calibration phase. The method may additionally include generating integral non-linearity compensation values based on the frequency differences measured. The method may further include generating the applied frequency control signal based on a frequency control calibration signal value received by the digital-to-analog converter during the calibration phase. The method may also include generating a compensated frequency control signal value based on a frequency control signal value received by the integral non-linearity compensation module and an integral non-linearity compensation value associated with the frequency control signal value during an operation phase of the wireless communication element.
