Abstract: front page image
(EN)A current reference circuit comprises a positive temperature coefficient circuit and a negative temperature coefficient circuit, the temperature coefficients of which can be adjusted to give a temperature independent output current. The base of a transistor in the positive temperature coefficient circuit is connected to the base of a transistor in the negative temperature coefficient circuit to bias it.
(FR)L'invention concerne un circuit de courant de référence. Ce circuit comprend un circuit à coefficient de température positif et un circuit à coefficient de température négatif, dont les coefficients peuvent être ajustés pour donner un courant de sortie indépendant de la température. La base d'un transistor dans le circuit à coefficient de température positif est reliée à la base d'un transistor dans le circuit à coefficient de température négatif pour le polariser.
