Patent ID: 7265636

Claim:
A phase-locked loop device comprising: two inputs for receiving two input signals; a charge pump having two opposing currents flowing therein, said charge pump connected between said two inputs; a filter; a calibrator, activated by an activation signal and deactivated by a deactivation signal, for equalizing an output voltage of the charge pump with an input voltage of the filter and amplitudes of the two opposing currents flowing in the charge pump; and a controller comprising a delay cell for delivering two delayed signals based upon the two input signals, a control circuit for delivering, respectively and successively, and in the presence of the two delayed signals, two interruption signals to the charge pump to cause respective, successive interruptions of the two opposing currents, and an activation/deactivation unit for delivering the activation signal prior to each occurrence of a first one of the two input signals, and the deactivation signal following the interruptions.
