Method and device for phase and frequency comparison

Phase and frequency comparison device, according to reference signal (Sref) of frequency (Fref) and phase of function, for control frequency control oscillation device of output signal of frequency (Fvco) and phase, the comparison device including device (11,12,21,22), for detection reference signal (Sref) and oscillator signal in the the signal of frequency and phase of changes representative value; device (S1+,S2-,16,17), for in detection changes Shi produced first or second signal; device (S2 +,S2-,24-27), respectively in the first or second signal is used to detect changes in the third or fourth signal for all signals (Io;Vo) adding the oscillator device and device (13,23), used respectively in the first and second or third and fourth signals simultaneously, first and second signal is stopped, or all of these signals.
