Claim 8:
9. A method for generating a delay-compensated output signal responsively to a non-compensated output signal, the method comprising:
generating the non-compensated output signal using a controlled oscillator;
using a main feedback path comprising a phase detector and a loop filter, generating a main feedback signal responsively to the delay-compensated output signal, and controlling the controlled oscillator using the main feedback signal;
using a delay-compensation feedback path, generating a delay-compensation feedback signal that is indicative of a sum of (i) a first delay from an output of the controlled oscillator to an input of the phase detector and (ii) a second delay from an output of the loop filter to an input of the controlled oscillator; and
using a phase interpolator, which is controlled by the delay-compensation feedback signal, generating the delay-compensated output signal with a phase that is set to compensate for the sum of the first delay and the second delay.
