发明名称 METHOD AND CIRCUIT FOR ADJUSTING THE FREQUENCY OF A CLOCK SIGNAL
摘要 In a general aspect, a method for adjusting an oscillator clock frequency can include applying a first control value to a first oscillator, applying a second control value, different from the first control value, to a second oscillator, measuring a frequency of each of the first and second oscillators, determining, by interpolation, a corrected frequency measurement of the second oscillator depending on a frequency deviation measured between the first and second oscillators when subjected to a third control value, on the third control value, and on the control value applied to the second oscillator, determining by interpolation a new first control value depending on the measured frequency of the first oscillator, on the corrected frequency, on the first and second control values, and on a desired frequency, and applying the new first control value to the first oscillator.
