ABSTRACT:
A circuit supplies a current (I) in which the current variations (I.sub.L) having been equalized according to a given relationship. In order to obtain an equalization characteristic having at least two slopes, the circuit uses the switching of the current sources (xI.sub.o, yI.sub.o and zI.sub.o) by means of switching stages (T.sub.1, T.sub.2, T.sub.14). The output current I passing through the current output stages T.sub.3 and T.sub.4 thus fluctuates between two levels according to the desired equalizing relationship.
