A phase interpolator receiving a first signal having an oscillation frequency Fin and providing a second signal having said oscillation frequency and having a phase shift &#x394;&#x3c6; with respect to the first signal which depends on a third signal. The interpolator includes a variable phase-shifter receiving the first signal and providing the second signal, the phase-shifter circuit includes an oscillator having a variable natural frequency Fo controlled by a fourth signal; a phase comparator capable of receiving the first and second signals and of providing a fifth signal representative of said phase shift; and a unit capable of providing the fourth signal which depends on the third and fifth signals.
