Abstract:
An integrated circuit comprisinga series of layers formed by low-resistance materials called conducting layers,separated in pairs by layers of insulating material called insulating layers,which integrated circuit includes a first capacitive element offering between a first and a second terminal a capacitance of fixed value,the first capacitive element being formed by a stack of conducting plates cut out of the conducting layers and electrically insulated from said layers,characterized in that:the first capacitive element comprises as many conducting plates as the integrated circuit comprises conducting layers,the first and the second terminal of the first capacitive element being connected to the conducting plates that form the ends of the stacka first bulk which has a given type of conductivity is installed inside the substrate so that the stack that forms the first capacitive element is superposed on said bulk,which bulk is connected to the surface of the substrate covered by said stack via an area that has the same type of conductivity type as the bulk.
