Classification: CPC H  G | IPC G  H

Claim 0:
1. A method comprising:
receiving, at a comparator, an output of a sampling phase detector of a phase locked loop, the output of the sampling phase detector of the phase locked loop also being supplied as a control source for a proportional control input of a voltage-controlled oscillator;
supplying an output of the comparator as an input signal to a calibration loop of a digital-to-time converter;
supplying an output of the digital-to-time converter to an input of the sampling phase detector; and
supplying the output of the comparator as a control source for an integral control input of the voltage-controlled oscillator,
wherein a circuit path between the comparator and the integral control input of the voltage-controlled oscillator is devoid of a transconductance amplifier.
