  • Patent number: 6348823
    Abstract: A digital controlled oscillator (DCO) of a digital phase lock loop (PLL) is disclosed, wherein a fractional DCO structure is employed to provide the required target clock for comparing with the generated output clock. Comparison results of phase differences then enable a K-counter loop filter for changing its stored value. A control logic circuit is enabled to control a tapped-delay line for adjusting the currently output 'clock to coincide the requirement of the target clock when the stored value increases/decreases to K/−K. Additionally, signals from all-digital counter filter can be input to the fractional DCO structure to calibrate the frequency of the target clock according to environment without additional circuits.
