Abstract
A clock distribution circuit and a method thereof. The clock distribution circuit comprises a comparator, a filter, a scaling unit, and an oscillator. The comparator compares a reference signal and a feedback signal to generate an error signal. The filter is coupled to the comparator and outputs a filtered signal based on the error signal. The scaling unit is coupled to the comparator, and scales down the filtered signal by a scaling factor to form a control signal. The oscillator is coupled to the scaling unit, and produces the feedback signal based on the control signal. And the scaling factor is less than 1.
