ABSTRACT:
A process for compensating a circuit including at least one first conductor with a specified potential, at least one second conductor generating disturbances on the first conductor by capacitive coupling, and a first bus with a reference voltage, coupled capacitively to the first conductor. The process includes the following steps: measuring of the current flowing on the first bus upon the application of a voltage to the second conductor; integrating a measured current to obtain a compensation voltage to be applied to the first conductor; and applying the compensation voltage to at least one of the rows via the compensation conductor bus, the compensation bus coupled capacitively to the rows.
