Patent FR-2538577-A1 (FR)
Title: Circuit de source de courant de precision
Inventor: PLASSCHE RUDY JOHAN VAN DE
IPC: H03F3/343
Filed: 1983-12-23
Abstract: Un circuit de distribution de courant 1 délivre plusieurs courants essentiellement égaux i1, i2, i3 et i4 à un circuit de permutation 13, qui transmet ces courants à permutation cyclique aux sorties 18, 19, 20 et 21. Les courants apparaissant à ces sorties présentent une ondulation, qui est provoquée par l'inégalité du courant i1, i2, i3 et i4. Un circuit de détection 30 assure la détection de la composante d'ondulation des courants i1, i2, i3 et i4 et l'amène à un circuit de réglage destiné à ces courants du bloc de circuit de réglage 50. Le circuit de réglage en question délivre un courant de réglage permettant de corriger le courant en question i1, i2, i3 ou i4 de façon que la composante d'ondulation disparaisse pratiquement.
