Abstract
A controllable assembly of current sources includes several first output terminals, with a first transistor associated with each first output terminal, the current on each first output terminal depending on the current flowing through the first transistor, and a circuit configured, in response to a predetermined variation of a control voltage, to successively progressively turn on, then progressively turn off, each first transistor. The first transistors are MOS transistors, and each first output terminal is associated with a current mirror formed of MOS transistors, the current mirror providing to the first output terminal a current depending on the current flowing through the first transistor.
