Claim 0:
1. Electronic circuitry, comprising:
a semiconductor switching element;
a first capacitance for holding a first voltage;
a first resistive element and a first switch connected in series between a first terminal of the first capacitance and a control terminal of the semiconductor switching element;
a second switch connected between a second terminal of the first capacitance and the control terminal of the semiconductor switching element;
a second resistive element and a third switch connected in series between the second terminal of the first capacitance and a first terminal of the semiconductor switching element;
a second capacitance having a first terminal connected to the second terminal of the first capacitance;
a fourth switch connected between a second terminal of the second capacitance and the first terminal of the semiconductor switching element; and
a driving circuit configured to
turn on the first switch and the third switch and turn off the second switch and the fourth switch in a first period, and
turn off the first switch and the third switch and turn on the second switch and the fourth switch in a second period supply.
