Abstract

L'invention concerne une pompe de charge pour boucle à verrouillage de phase comportant une première source de courant (14), une deuxième source de courant (16), plusieurs commutateurs (M1, M2, M3, M4) propres à mettre en communication la première et/ou la deuxième source de courant avec la sortie (OUT) de la pompe de charge. La deuxième source de courant est commandée par un moyen de commande (18) propre à mémoriser une grandeur correspondant à la valeur du courant (I1) fourni par la première source de courant (14), de sorte que la valeur du courant (I2) fourni par la deuxième source de courant est sensiblement égale à la valeur du courant (I1) fourni par la première source de courant.
