Abstract
A device for regulating a voltage of an electric current supplying an integrated circuit resting on a substrate. The integrated circuit comprises a ground terminal and a power supply terminal able to receive the electric current. The regulation device comprises a first cover covering the integrated circuit, a second cover covering the integrated circuit. The first cover is electrically connected to the power supply terminal of the integrated circuit. The second cover is electrically connected to the ground terminal of the integrated circuit. The first cover and the second cover are connected together by a capacitive connection.
