A driving circuit including a reference voltage generator to generate a reference voltage based on an operating frequency of a complementary circuit; a comparator including a first input configured to receive a drain-to-source voltage of a field effect transistor; and a second input to receive the reference voltage; and a signal generator to deliver a driving signal to a gate terminal of the field effect transistor to drive the field effect transistor to an ON state after the drain-to-source voltage of the first low side field effect transistor becomes less than the reference voltage and to an OFF state after the drain-to-source voltage of the field effect transistor becomes greater than the reference voltage.
