Abstract
A phase lock loop device further includes a probability shaping device provided between a phase detection device and charge pump and loop filter (CPLF) device. The probability shaping device operates to reduce the frequency of outputting up-index or down-index; thereby shaping probability distribution to reduce degradation due to mismatching of the CPLF device.
