Abstract: An all digital phase lock loop is disclosed, including a digitally controlled oscillator, a phase detector, and a loop filter. The digitally controlled oscillator is controlled by an oscillator tuning word to generate a variable signal. The oscillator tuning word includes a first tuning word and a second tuning word, where the frequency range of the digitally controlled oscillator, capable to be adjusted by the second tuning word, is broader than that capable to be adjusted by the first tuning word. The phase detector detects a phase error between the variable signal and a reference signal. The phase error is received by the loop filter to output the oscillator tuning word. The loop filter has several stages of the low pass filters and a modification circuit. The modification circuit detects two filter outputs from two low pass filters among the filters and accordingly adjusts the second tuning word.
