ABSTRACT:
In an integrated circuit, a central reference generator (3) generates a setpoint signal determining the operating characteristic required to be common to some of the functional components of the circuit. Lines (4-1 to 4-n) distribute this signal among units of the circuit, each unit comprising a functional Component (2-n). In each unit, a local adjustment circuit (5-n) receives the setpoint signal and generates an adjustment value. Correction circuitry adjusts the operating characteristic of a device in the local adjustment circuit (5-n) as a function of the adjustment value. The device is placed in proximity to the functional component and configured in such a way that the operating characteristic which is thus imposed on the device is also imposed on this component.
