A circuit includes a first and a second solid state electronic device arranged in a bridge-leg configuration, each selectively operable as a control switch and synchronous switch and each selectively operable in an ON state and OFF state. A driver circuit is operably connected with at least the first solid state electronic device for controlling operation of at least the first solid state electronic device. A signal modulation circuit is operably connected with or between the driver circuit and the first solid state electronic device and includes an input operably connected with the driver circuit, an output operably connected with the first solid state electronic device, and a variable resistance circuit operably connected between the input and the output and operably connected with the driver circuit. A resistance of the variable resistance circuit is adjustable by the driver circuit to prevent spurious operation of the first solid state electronic device.
