A circuit includes a MOS transistor having a control electrode and a control capacitance, and including a control circuit for the MOS transistor. The control circuit includes an input to supply a control signal and an output to supply a drive signal, the output being connected to the control electrode of the MOS transistor. A calibration circuit is connected to the control electrode of the MOS transistor, and generates a calibration signal dependent on the capacitance value of the control capacitance. A drive circuit generates the drive signal with an amplitude dependent on the calibration signal as determined by the control signal.
