Abstract:
A method for adjusting a phase of a sampling frequency of ADC is disclosed. The method includes converting an analog signal into a first digital signal according to a first phase of the sampling frequency during a first time interval; calculating a first value according to the first digital signal; converting the analog signal into a second digital signal according to a second phase of the sampling frequency during a second time interval; calculating a second value according to the second digital signal; and adjusting the phase of the sampling frequency according to the first value and the second value.
