A device (ES) for distributing power between n cathodes (Ki) of at least one multipolar stimulating electrode (EM) comprises at least one anode (A), wherein n is equal to or greater than two. Said device (ES) comprises a reconfigurable current mirror (MC) which is provided with n outputs (K'i) connectable to said n cathodes (Ki), respectively and supplies to the n (K&#x2032;i) outputs n complementary fractions of a control current having respective selected values which are substantially constant at the control current amplitude variation in order to carry out a substantially constant spatial location of stimulation.

A device for self-testing of an analog-to-digital converter includes elements for applying to the converter test signals and analyzing elements. The analyzing elements include common resources ( ) integrated in the circuit bearing the converter and capable of being configured to determine successively shift, gain and non-linearities of the converter and elements for configuring and controlling the common resources ( ) so as to adapt them to the characteristics to be determined.
