摘要： A phase locked loop is disclosed and includes a frequency divider circuit with a settable division ratio in a feedback path. The division ratio is produced using a control circuit which, besides an input for supplying the integer and fractional components for the frequency division ratio which is to be set, includes an input for supplying a phase correction signal. To produce the phase correction signal, the phase locked loop further includes a phase correction apparatus. The phase correction signal preferably contains a signal component with an exponential profile, and is supplied to the control circuit for producing a frequency division ratio for the frequency divider circuit such that it compensates for a phase drift in the output signal from the voltage controlled oscillator in the phase locked loop.
