ABSTRACT:
There is provided an analog phase locked oscillator comprising a sampling phase detector, a loop filter, a voltage controlled oscillator, a frequency multiplier and a feedback loop where the feedback loop connects the output of said oscillator with the input of said phase detector through said frequency multiplier. The sampling phase detector is adapted to perform a discrete phase comparison between a reference frequency and the multiplied feedback signal. The voltage controlled oscillator is adapted to give out a constant frequency at a multiply of the reference frequency divided with the multiplication factor of the multiplier.
