Cascode switch circuit including level shifter

A cascode switch circuit comprising:

• a normally-on transistor connected to a drain terminal;
• a normally-off transistor connected to a source terminal, the normally-off transistor being connected to the normally-on transistor in cascade form;
• a level shifter configured to change a voltage level of a switching control signal applied to a gate terminal and provide the changed switching control signal to a gate of the normally-on transistor, the level shifter being connected between the gate terminal and a first resistor;
• and
• a buffer configured to delay the switching control signal and provide the delayed switching control signal to a gate of the normally-off transistor, the buffer being connected between the gate terminal and the gate of the normally-off transistor
• wherein the first resistor is connected between the level shifter and the gate of the normally-on transistor.
