    Abstract: The present disclosure relates to a method for measuring a capacitance of a pair of electrodes including charging the pair of electrodes and transferring the charge between the pair of electrodes and a sampling capacitor, and a measuring step representative of the capacitance of the pair of electrodes according to the voltage at the terminals of the sampling capacitor according to the number of cycles executed so that the voltage at the terminals of the sampling capacitor reaches a threshold voltage. According to the present disclosure, the method comprises an initial step of charging the sampling capacitor between a first voltage and a second intermediate voltage in between the first voltage and a third voltage greater than or equal to a ground voltage, the pair of electrodes being charged between the second voltage and the third voltage. The present disclosure applies in particular to the control of a touch pad.
