Circuit comprising a MOS transistor and a control circuit for the MOS transistor

摘要

The invention relates to a circuit comprising a MOS transistor (10) having a control electrode (G) and a control capacitance (11), and comprising a control circuit for the MOS transistor (10), having:
an input to supply a control signal (Sin) and an output to supply a drive signal (S20), the output being connected to the control electrode of the MOS transistor (10);
a calibration circuit connected to the control electrode (G) of the MOS transistor (10), and being adapted w to generate a calibration signal dependent on the capacitance value of the control capacitance;
a driver circuit (20) being adapted to generate the drive signal (S20) with an amplitude dependent on the calibration signal (S30) as determined by the control signal (Sin).
