摘要： A clock trimming apparatus includes an oscillator, a judging unit, a latching unit, and a tracking unit. The oscillator has an input terminal receiving a bias signal and an output terminal generating a clock signal. After a frequency division is performed on the clock signal, the judging unit generates a frequency-divided signal. If the frequency-divided signal matches the reference signal, a pass signal generated by the judging unit is activated. The latching unit is used for generating a trimming completion signal. After the pass signal is activated, the trimming completion signal is activated. The tracking unit is used for counting a pulse number of the reference signal and providing the bias signal to the oscillator according to a trimming code. After the trimming completion signal is activated, the trimming code is stopped being adjusted.
