Electronic circuit having adjustable transistor device

An electronic circuit, comprising:

• a drive circuit;
• and
• a transistor device comprising:
• at least one first type transistor cell comprising a drift region, a source region, a body region arranged between the source region and the drift region, a drain region, a gate electrode adjacent to the body region and dielectrically insulated from the body region by a gate dielectric, and a field electrode adjacent to the drift region and dielectrically insulated from the drift region by a field electrode dielectric;
• a gate terminal coupled to the gate electrode of the at least one first type transistor cell, a source terminal coupled to the source region of the at least one first type transistor cell, and a control terminal configured to receive a control signal;
• a variable resistor connected between the field electrode of the at least one first type transistor cell and one of the gate terminal and the source terminal, wherein the variable resistor comprises a variable resistance that is configured to be adjusted through the control signal received at the control terminal;
• and
• a first switch connected in series with the variable resistor, such that the variable resistor and the first switch are connected in series between the field electrode and the one of the gate terminal and the source terminal, wherein the first switch is configured to be driven dependent on a drive signal received at the gate terminal of the transistor device,
