Abstract
Le procédé de lissage du courant consommé (Ivdd) est basé sur une suite de recopies de courant (4, 5, 7) et sur une source de courant (61) délivrant un courant de référence (Iset), lesdits courants étant transformés en une tension de référence pour la régulation d’un moyen de régulation (81) de façon à ce que le courant consommé (Ivcc) vu de l’alimentation ne dépende que du courant de référence (Iset). Figure pour l’abrégé : Fig 1
