Phase-locked loop with course providing damping and natural frequency independence

摘要

A phase-locked loop includes a switched phase detector, a loop filter and an oscillator connected in series, as well as a device for technology compensation, in particular a course control device. An operating point is adjusted during a starting phase of the phase-locked loop through the use of the course control device in such a way that the damping and natural frequency of the phase-locked loop is independent of fluctuations in technology parameters.
