Abstract
A frequency compensation circuit determines a target calibration count of a fixed capacitor coupled to a processing device. The frequency compensation circuit identifies a current calibration count of the fixed capacitor. The frequency compensation circuit determines that the current calibration count satisfies a threshold criterion associated with the target calibration count. In response to determining that the current calibration count satisfies the threshold criterion, the frequency compensation circuit adjusts a frequency of an internal oscillator of the processing device based on the current calibration count and the target calibration count.
