Abstract
A phase locked loop is disclosed. One embodiment includes a phase comparator having two phase comparator inputs and a phase comparator output. A filter having a filter input and a filter output is provided, wherein the filter input is connected to the phase comparator output. A voltage controlled oscillator has a first oscillator input and an oscillator output. The first oscillator input is connected to the filter output and the oscillator output is connected to a first of the two phase comparator inputs. The oscillator has a second oscillator input. A coupling element is connected in parallel to the filter and arranged between the phase comparator output and the second oscillator input in such a way, that an output signal of the phase comparator is amplified and input to the second oscillator input.
